    The Felt DD Thread - DD70, DD30 and DD10

    There is a bit of info here and there about these fatbikes, but nothing centralized in one thread. So let's start a thread about all things Felt fatbikes. Mods that work, mods that don't work and things we like and don't like about them.

    Here is a thread that was started specifically about the DD70, but spilled into the DD30 as well. It's been dormant. I'm putting it here because it contains useful info about the two models.

    http://forums.mtbr.com/fat-bikes/fel...-a-947758.html

    There are three models for 2016: the DD70 (black), the DD30 (blue) and the DD10 (army green).

    I've owned a DD30 for a few months now. I really like it. To me, the bike is well spec'd at a good price.

    I find the Deore brakes to have excellent modulation. The carbon bar dampens vibration very well. The 15x150 and 12x197 thru-axle hubs allow for Bluto and tire upgrades. The Jumbo Jim 4.0s supplied with the bike roll well, are very light and I find them to be great all-around tires. They will be replaced by a second set of tires for winter riding (Nates for the time being, but likely something bigger soon now that I own a fatbike that can take bigger tires).

    I like the way it rides, and I like the way it looks.

    I added a few purple parts to the bike. Straitline De Facto pedals, Salsa seat collar, Salsa stem cap, and some purple Duck tape on the rims for good measure:

    I went on a short bikepacking trip a few weeks back and tried fitting a rear rack to carry some of my gear. First, I tried to fit an Axiom Fatliner rack, but the rack does not fil properly, at least not stock. The Axiom rack sat way too high up, as high as my saddle. This is because the Fatliner rack is made to be attached to eyelets that are located where the chainstays and seatstays meet, right above the QR or thru-axle. The DD30 has eyelets that are located higher than that, on the seatstays, right above the brake calipers.

    I found a rack that works well with the DD30, at least with my small frame: the Surly rear rack. It clears the 4.0 tire with a ton of room to spare. I bent the rack sides outward just a tiny bit (it's steel, so it's all good) so that I could attach the rack to the eyelets on the inside of the frame. I used V-brake spacers to fill in the gap between the frame and the rack.

    The rack arms that came with the Surly rack were too short, so I used the Axiom rack arms instead (280mm long).

    I have a few questions for fellow DD owners:

    - Has anyone gone tubeless with the stock rims?

    - How do Bud/Lou or the Beists fit in the frame?

    The DDs seem to be popular in Europe. I found DD threads on MTB forums in Germany and Finland. I can't read either language, but Google translate does an OK job. You get the gist anyway .

    Felt Double Double | MTB-News.de

    Felt Double Double

    I was going through the German thread and found pictures of a DD30 with Jumbo Jim 4.8s on stock rims (at p. 37) :

    In that post, the guys says the JJs were mounted with tubes, at 14.5 PSI (1 bar), the tires measured 112mm wide, 755mm height. He said there is a slight chain rub in lowest gear.

    This other guy (at pp. 38 and 40 of the same thread) put Jumbo Jim 4.8s on 90mm rims. He claims they fit well (no mention of rubbing), the tires were measured at 113mm wide and there was a 7mm clearance on each side of the frame. See for yourself:

    OP: what's your height/inseam?

    I've seen the bike in person and the paint job is amazing.

    I'm 5' 7" with a 30" inseam. I ride a small. The DD has a long effective top tube. I tried a medium and it's too big for me, even with a short stem.

    I agree, the paint job is striking.

    I couldn't resist posting another picture from the German thread (at p. 35). Here is a DD30 with BFLs on silver Clown Shoes:

    We're the same height but 28" inseam. Do you have clearance? This is what worries me the most. I wished Felt would re-think on making XS sizes in their FBs.

    I have standover but obviously not as much as on some other fatbikes with sloping toptubes à la 9zero7, Norco, etc.

    With a 28" inseam at 5'7", you must have a long torso. IMO, you'd fit well on a small DD, but the only way to find out is to try one out!

    1. Tried several times to go tubeless with the stock rims - failed both times because of the silly little bead seat that is on this rim. It is narrow and rounded - so while at high pressure (15 psi), it will pop onto the seat and stay on - the tire literally falls off the bead as you lower pressure < 10psi.

    The solution was to buy a set of DT BR2250 wheels.

    2. This guy fits a lou on a Nextie 90mm rim and still has clearance.
    The Felt DD Thread - DD70, DD30 and DD10-img_6457.jpg

    There is even more clearance in the fork.


    I love my DD30. Bought it in Feb 15 and ended up riding it all summer. I've added BR2250 wheels, a Jones loop bar and a Chinese carbon fork.


    I've weighed many of the parts, but have the listing at home. Off the top of my head:
    Bars: 175g
    Fork: 1400g (with steerer for XL frame)
    Front wheel: 1450g
    Rear wheel: 1600g
    and my JJ 4.0 tires are just over 1100g each.

    Hey Scot, I'd seen your post on the Fat Bikes FB page last night and thought it'd be great to see your input here! Nice upgrades you've done to your bike. What's the fork like? Is this an Ebay find? It'd be great if you could list the other parts you've weighted when you get a chance.

    So, based on your experience, it's possible to run the stock wheels tubeless, just not a low pressures... Which kind of defeats the purpose, doesn't it! What techniques did you try? Did you try it with the JJs 4.0 or with other tires? I've read about a guy on a French Mtb forum who was able to set them up ghetto tubeless, but there was no mention about running low pressures...

    Good to know that Lou fits in the back. There's no issue running Bud up front, the stock fork is so wide! A friend of mine runs Bud and Lou in the winter, I'll see if I can borrow them for a few days to try 'em out when we get snow.

    The fork was $180 from a supplier that posts in the FB fatbike forums - but I'm not ready to recommend it just yet. It's built well except I don't like the axle they sent with it - its diameter is slightly smaller than the 12mm axle that comes with our forks - and the thread is different. This bugs me because it leaves a little "slop" between the axle and hub interface which makes it necessary to rely on the clamping load of the skewer to keep the front wheel tight. The axle has a weird / clunky / delicate interface that seems like it could break easily if it was over-tightened.

    With respect to running tubeless on the stock wheels - I don't know if I would trust the tires to stay inflated when I rode it. I only had tried it with the Jumbo Jims - but I currently am using the rims to hold a set of snowshoe XL's while I stud them. I was going to take a video last night while I pulled the valve core and the tire deflated to see if it fell off the rim as it deflated. If I have time tonight, I'll give that a try to see how the Vee Rubber does.

    Thanks for the info! For the time being, I replaced the tubes with extralight Q-tubes (made by Kenda) at about 250g. each. The rest of the bike is stock.

    How did the Snowshoe XLs hold up? Did you have better luck than with the JJs?

    Are you happy with the DT Swiss wheelset?

    I haven't run the XL's yet - waiting for snow.
    My JJ's are still doing awesome and don't show much wear for ~500 miles of use.

    Super happy with the wheelset - noticed an immediate difference in how the bike rode, but to tell you the truth, the OEM wheelset is still pretty sweet - and tempting me to build another bike around them.

    Nice bike! The black frame looks great. Is that a 100mm or 120mm Bluto?

    I was able to borrow Bud and Lou for a few days, great fit on the stock rims. No rubbing at low pressures (about 4-5 psi). It was my first experience on 5" tires. Needless to say, it was very positive!

    I also added a basic KS eTen-R dropper post. I like it. It works well so far all the way to -10C. It slowed down for me at -15C, but it still worked.

    Here is a pic taken this morning in Gatineau Park, Québec.

    Kryten, both 27.5+ and 29+ should fit. The bike was designed to take 26x4.8s like Bud and Lou. There is absolutely no issue with respect to a 27.5+ 3" tire, which is approx. equivalent in diameter to a 26x4.0" tire. It should also fit a 29+ 3" tire, which is just a little taller than a 4.8".

    The Felt DD Thread - DD70, DD30 and DD10-15_sept_ontheplusside_header2.jpg

    For example:

    A Nate on an 82mm rim is said to measure 749mm in diameter.
    A Bud on an 82mm rim is said to measure 762 in diameter.
    A Knard 29x3.0 tire will have a diameter or 779.4mm (at 19psi).
    A Knard 3.0 tire on a Velocity P35 will have a diameter of 778.6mm.

    Oh, yeah, since we're on the topic of tire sizes that fit on the Felt, it seems that you can fit a 26x 5.05 2XL up front:

    Update on my DD30, 7 months in

    An update on my Felt DD30:

    I bought a DD30 in October and enjoyed riding it on trails waiting for the winter to arrive here in the Northeast. I went out and bought a set of Vee Snowshoe XL Studded 4.8" tires so I could attack both trails and roads in the ice-fest that southern New England (particularly near the coastline) is famous for -- further north, there's minimal icing because things don't thaw and re-freeze as often.

    Of course, the winter was a complete bust after three brutal winters in a row. I went out in all three of the storms that dumped more than 1" in our area (only one was decent at 8") so I put a grand total of about 27 miles on the $320 worth of snow tires, about the same cost per mile as driving a Lamborghini Aventador. Sigh.

    In early March, I saw a blog post with some orange 4.0" tires, which I first thought were a little ridiculous, but which I eventually realized were a great complementary color to the blue paint on the DD30. Took a surprising amount of effort but I was finally able to track down a pair, though I don't think they'll have any more because they seem to have made a small batch as a one-off, rather than introducing it as an ongoing product.

    I ended up accessorizing the bike with orange bottle cages and grips, orange and blue bottles and with Crank Brothers Double Shot pedals (in orange), which have SPD clips on one side and platforms on the other, giving me flexibility in how I ride. Now I can bomb around town in Nike's or I can clip in for longer rides, which is really cool. The original tubes had orange screw-on caps, which was a nice extra. I thought about orange rim strips but a) Surly is out of stock for the season and b) it probably won't look good if the color of the strip and tire are not a close match.

    Am still happy with the bike. The common complaint of rims that won't support tubeless is not relevant to me since I haven't yet decided to take the leap. I'm thinking that I may rebuild the wheels in the fall, mostly to get a Shutter Precision fat bike dynamo on the front, making it easier to ride at night in winter, in case I get caught out late coming back from a ride. If I'm gonna do that, then I should also get the rear wheel hand built at the same time just to make it last longer, since I'm 6'0" and 250 and tend to trash wheels. At that point, given the cost of the gen hub and the labor to rebuild the wheels, it's no big deal to put tubeless-ready rims on there.

    Wow KidCharlemagne, I dig the orange and blue combination!

    I've used Deore LX and XT Shimano dynamo hubs on my commuter bikes for the past 6 years. I've paired them up with B+M lights. I'm very happy with them. I've heard great things about SP dynamos, I have no doubt you'd be happy with it.

    One thing that I've noticed with my Shimano dynamo hub+B+M combo is that at low speed, the LED light doesn't really shine, it flickers. This happens, for example, when I'm climbing a steep hill. If you're a slow, diesel-type climber, you might find this flickering annoying. If you're a mountain goat, though, this would be a non-issue

    I'm not sure about the DD10, but I was able to make an internal dropper work on my DD30. I'm using a 30.9mm Thomson post with the cable routed through the old front derailleur holes.

    hi scot,

    thanks for reply

    yeh thats what i was thinking, running the cable through the holes for the front derailer, ive never fitted cables internally before, is it easy enough to do, any special tools needed?

    My local dealer seems to think its a 34.9 seat post, but on the Felt website it says:

    Felt carbon shaft w/ forged head, micro-adjust, 15mm offset, Ø30.9 SM (350MM) MD/LG (400MM)

    so ive emailed Felt direct, just awaiting a reply

    cheers

    Well, as i typed this I recieved a response from Felt:

    The DD10 fatbike is not able to accommodate a dropper post with internal cables. It doesn’t have the proper access from the down tube into the seat tube.

    How did you manage to install yours?

    cheers!

    If you take the bottom bracket out, you can see where both downtube and seattube extend into the BB shell. I notched the tubes with a dremel grinder to let the cable transition / bend easier. The DD30 comes with a front derailleur that I removed to go 1x10, so I had the openings in the frame for that - I don't know how that's done on the DD10 with 1x already used.

    Thanks again :-)

    On my DD70 I'm using a KS Supernatural dropper and its 30.9mm The cable is external so I can't help you there.
    With the right tool (16-notch 44mm OD) the Bottom Bracket just screws out. Remember the drive side is left hand thread.
    Edster75 had an issue with the threads in his bottom bracket being booger-ed up when he took it off for the first time.

    Oh, yeah, since we're on the topic of tire sizes that fit on the Felt, it seems that you can fit a 26x 5.05 2XL up front:

    Did you happen to weigh the stock tubes? I'm curious what the weight difference is.

    Have any DD30 owners gotten their seatpost replaced as part of the recall? I'm curious if the replacement is still carbon fiber or if it's something less desirable. http://www.cpsc.gov/en/Recalls/2016/...ber-Seatposts/

    I have not - I have a dropper and I put a thudbuster on my GF's DD30 - so I have two CF seatposts I need to take to a felt dealer and get replaced. The post on the 2016 is aluminum, so I'd bet that's what the replacement is.

    Tubeless

    Hi, my first post here. I've read the discussions and taken on board advise from yee guys. Thanks.
    I've had the same problem getting the tyre to seat tubeless on the tiny bead wall without high pressure. I even filled the centre cavity with foam and tape. No good.
    I resorted to rebuilding, so I kept my standard hubs. Rebuilt the wheels with good quality DT swiss spokes and 80mm Mulefut rims.
    Perfection!
    Mounted 4.8 Maxxis Minions.
    Currently running 8psi rear and 9 front with the bluto.
    Now tubeless is a breeze & loads of clearance for the 4.8s.

    Great looking bike! Pedals and cages complement well.

    Also, the new models are up on the website.

    Other two new colors I don't really care for, however, I think this looks killer.

    I see no real details on exactly which rims they've used. But hopefully they've changed. It cost me plenty to rebuild my wheels so I could go tubeless.

    Has anyone put hydros on a 70? Curious about spacers for the caliper mounts. Thanks in advance.

    I put a set of Shimano SLX M675 brakes and RT66 rotors 180mm front and 160mm rear.
    Just reused the spacer that came with the bike for the front. No spacer needed for the rear.

    Cool thanks. How is it routing the brake line thru the frame? I don't have my bike yet it's on it's way so I can't visually see how it would be. I'm guessing they fit just fine.

    It was easy. I just attached/taped the new brake line to the old brake cable housing and pushed the new line threw the frame while gently pulling out the old cable and housing. Then I cut off the extra line, put on an olive and the connecting insert, reconnected the line to brake lever, and bled the brakes.

    Zee 4pots fit grand too.
    Just be careful with that rear bolt on the back brake.
    It's difficult to get at as its close to the frame. can be easy to crosstread and damage the frame mount.

    That rear caliper mounting screw was a pain.
    I started the screw with my fingers to be sure it wasn't cross threaded. I used a hex bit in a 1/4" socket and a long 1/4" drive extension to clear the frame to tighten it with a ratchet.

    So the line will fit thru the frame with the banjo fitting on it then, that is what I was curious about more than anything else. I should have my bike in a few days. I cant wait. First fat bike.

    No the banjo fitting won't fit threw the frame.
    The brakes came with an extra olive and connecting insert but no extra banjo washers. So I left the banjo fitting on the caliper alone. I cut off the fitting that attaches to the lever and taped the new brake line to the old brake cable housing and fed it threw starting from the rear of the bike.

    I got them from JensonUSA. They were $59 a set. Looks like prices have gone up a little since then.

    I'm interesting by your modification about the rim to convert in tubeless. Is it possible to keep with the same spoke when you install the mulefut rim ?
    Did you have the parts number of the DT spoke ?
    Regards

    Hi Bzh. I wouldn't bother using the old spokes. Just cut them out. The cost of the time to remove them all carefully wouldn't be worth the trouble. I've asked my local bike shop for the part numbers of the spokes and brass nipples. They didnt cost a lot as far as i think. So I'll let you know soon.

    Ok, thanks.
    I have tried to find the "erd" of the felt rim without success.

    Hi Everyone,

    First post here after lurking for a while- thanks to people in this thread for posting pictures and giving info already.

    NBD! Felt DD 10 - Imgur

    I picked up a DD10 a couple of weeks ago. I really, really like this bike a lot. I've taken this on a bunch of trails around the Twin Cities and the thing absolutely shreds like no fat bike I've ridden before. One thing that I wanted to pass on, because I didn't see this info on Felt's website or any other reviews, the wheels on all the DDs now are tubeless ready. My dealer told me this but having not seen anything confirming this I wanted to contact Felt directly and pass it on.

    Good news. The 2016 rims were terrible. No way you could keep the beed on that tiny edge at low pressure. Added a big cost to those of us who want low pressure tubeless.

    Bottom Bracket Drop is 65
    Bottom Bracket Height will depend on what wheels and tires you are running.

    Has anyone mounted 4.8" Big Fat Knards on a Double Double? Wondering if there's enough clearance without any rub. I'm looking for the widest tire I can get without any rub, mostly for street and occasional beach riding. Any additional confirmations that Buds and Jumbo Jims fit without rub?

    I have a 2016 DD30. I ran my friend's Bud and Lou on stock rims for a couple of weeks last winter. No rubbing. I also have been running JJs 4.8s on stock rims for a few months this fall. No rubbing either.

    Awesome, thanks. I wonder if there is more clearance on the 2016 than the 2015? I've got a 2015 DD30 and I recall someone on the thread earlier posting about JJs causing slight chain rub in the lowest gear on a 2015.

    I didn't think that there were differences between the 2015 and 2016 models, except for that recalled carbon seatpost. But I may be wrong. My bike is the first one in this thread

    I just changed to 4.8" Snowshoe XL studded on my DD30 for the winter (with the original 80mm rims) and had tons of clearance, so much so that I was starting to fantasise about 2XL, but that is probably a step too far.

    2016 model btw, and everything stock so far (2x10) and no chain rub, not even close.

    Bought a dd70 a few months ago and loving it. We have really sandy trails here so really helps massively with that.

    I want to put a dropper post on my bike i have a medium sized frame. I had some issues with the seat post however when I bought the bike originally as I couldn't drop the seat enough as the back of the thread where the water carrier bolts go in protrude in to the seat tube shaft not allowing the seat to drop further. I am worried this will also affect the dropper post.

    What options have you guys gone with , have any of you found this issue with the bolts?

    Cheers

    Ben

    I just finished installing a KS LEV DX 125mm dropper on my DD30. I have a medium frame as well and I had the exact problem you experienced. I can't recall exactly, but I think it was just a bit more than 22cm from the top of the seat tube down to the carrier bolts.

    So if you get a dropper that does not require to be inserted more than 22cm you should be fine, you can look at the measurements below:

    http://kssuspension.com/wp-content/u...DX-drawing.PDF

    I have my 125 all the way down to the collar with no issue. That is 201mm into the seat tube.

    Bottom line, if you buy a dropper that does not require to be inserted more than 22cm you should be fine.

    Having a problem with my dd, I can't seem to work out where it's coming from, but there is a really loud creaking noise that seems to be coming from inside the frame when I pedal. The harder I push down on the pedals (particularly the right one) the louder the creaking becomes. Going to take the bottom bracket off tomorrow to see if anything going on there.

    The noise is so annoying when riding especially being OCD.

    Has anyone experienced this at all and could anyone advise on what to check.

    Cheers in advace

    I would check the cranks, take them off and put some grease in there, I haven't had this issue on my DD30, but on other bikes with this issue it helped.

    Hey, this bike looks great, I am just in the process of fitting a suspension fork myself and I noticed that you still have the external lower spacer on. If you would like to get the same geometry as the DD10 then you should install this headset:

    FSA No.57 - Orbit 1.5 ZS Tapered - FSA

    I have spent so much time trying to figure out which headset is correct and finally with good help from Felt I got the correct one. Hope this can be of help to someone.

    I trashed the stock bottom bracket in under a year on my DD70. I was going to just replace/upgrade the bearings with angular contact bearings from RWC but the thread got buggered when I unscrewed the bearing cup. The thread was dry, no never seize or orange sealant. The other side had orange sealant and the thread was fine. I ended up buying a tap set from park tools and a new bottom bracket from RWC. It's better than new now!

    Here's a link to my thread.

    Yeah I did. I barely get a chance to ride so I'm sure he would smoke me too. Maybe we can get out together at some point.

    Hey folks, I have a 2015 Felt DD70. I love the fit and have made a few upgrades (carbon bars, SLX hydraulics).

    I'm about to go 1x11, but was curious if anyone has been able to run a narrower crankset than the RF ride. I only want clearance for Dillinger 5s/GC 4.6.

    Anyone with any experience or am i limited to the ~220 Q?

    Felt DD30 with Chains

    Hi,
    This is my first post on the site. Hope I get it right. I enjoy winter riding and thought I would add a picture of my Felt DD30.
    I have added a Rockshox Bluto and a One Up 42 tooth rear cog.
    The chains are brass plumbers chain about 40 feet long. Shock cords remove slack from chains.The Felt DD Thread - DD70, DD30 and DD10-img_0465.jpgThe Felt DD Thread - DD70, DD30 and DD10-img_0512.jpgThe Felt DD Thread - DD70, DD30 and DD10-img_0513.jpg

    I am now running an Aeffect crankset but it seems to be the same width as the Ride crankset. I think you are stuck with using a crankset that matches your 190/197 rear spacing. I doubt you could go any narrower without the crankarms hitting the chainstays.

    I resorted to rebuilding, so I kept my standard hubs. Rebuilt the wheels with good quality DT swiss spokes and 80mm Mulefut rims.
    Perfection!
    Mounted 4.8 Maxxis Minions.
    Currently running 8psi rear and 9 front with the bluto.
    Now tubeless is a breeze & loads of clearance for the 4.8s.

    I have the 2016 DD70 and now my front hub is starting to make a click sound every now and then. Has anyone here serviced the front hub? I am assuming there are cartridge bearings that need to be pulled out.

    I bought a DD30 last winter, nice to see a little activity here. I'm sorry bjosep, I don't know the answer to your question. Felt customer service can likely give you info on the hub spec: https://www.feltbicycles.com/Interna...ontact-Us.aspx

    Just to answer myself. There are caps over the bearings which are also the ones that extend out and sit inside the dropouts. These caps are screwed and there are two notches in them so you can fit a 19 mm spanner to untie (one of) them. To untie the second one I do assume that you need a 14-15 mm hex/allen key (possibly 3/5 inch, 15.24 mm) to hold the bearing housing (pipe) while you untie the second one. As I do not have access to one I haven't tried it so I am not sure which size is required.

    The bearings are cartridge bearings and seem to be 20 mm inner and 32 mm outer diameter. I haven't pulled them out so I do not know what their thickness is.

    I suppose the hubs are rather generic through axle hubs so someone here maybe can correct or confirm my thoughts on the allen key.

    i had exactly same problem, i managed to get the end caps off & i could see the bearing, however i have no idea how to remove the bearing as they are loged in both sides & the spindle would not budge, so i fired Felt an email & here is there response!

    "I do not have a DD10 to look at I person but I believe that is a “cup and cone” design. I do not believe they are cartridge style bearings. There should be a locknut holding down a cone that needs to be removed then the axle goes out the other side. It would be loose individual bearings. If you have not overhauled a hub before we suggest a local bike shop mechanic. Maybe YouTube would offer some guidance but officially Felt has to say it is best to have a bike shop mechanic do this."

    however they are sealed bearings as i can see them & the spindle/axle will not budge. To be honest not at all impressed with there customer service, my felt is the 2017 model yet they dont have a clear answer on how to replace bearings! ..anyway I bought some DT Swiss 2250 rims so problem solved! .. (nope i didnt buy them just because i coudnlt remove the front bearing from the stock rims!) i had already planned to buy DT Swiss rims & i want to keep the stock rims as spares so i still need to sort this bearing issue

    Another question, when does your felt fatty not be a felt fatty no more!?

    Just curious as i think the only thing left on my DD10 that its stock is the actual frame & the raceface crankset but rest is all changed! So is mine still a Felt DD10!? ^^

    The sizes are written on the bearing cartridges, just take it apart and you'll know.

    If you look on the outside of the cartridge/cage you should see in small letters the actual size and type of the bearing.

    On the original lower bearing one from my DD70 it says "TH MR170 1.5 45°x45° J6"

    The upper one should say something similar except 1 1/8 rather than 1.5

    If not, contact your LBS or Felt directly to ask for replacement.

    Picked up a NOS small 2017 DD70 this weekend on a closeout sale for $587 out the door. Its the charcoal/magenta (pink) model with 3x9. Think that's a decent deal for someone getting into fat bikes? I'm a very casual biker who didn't start until a couple years ago when I bought a used '09 GF Mullet on CL for $225 just to get into better shape and exercise more. Now I'm down a little weight, in better shape, and doing more riding and getting into bikepacking.

    Eventually I think I'll upgrade the brakes and go 1x11, still trying to wrap my head around that whole thing (gearing, which components I can keep to save $, component compatibility, etc)

    Congrats on the bike! That's a great price for a good entry-level fatbike. No need to hurry on changing components. Ride the heck out of it, figure out what works for you and what doesn't, read up on components (and take the plunge when your drivetrain is worn out!).

    Happy trails!

    Thanks, I've been able to take it out after work before it gets dark twice, unfortunately its only been 12 miles on paved bike trails, no snow, beach, or mtb trails yet. Fat bikes are definitely different but having a great time so far.

    I've been thinking more about 1x11 and want to get a list of stuff needed so I can keep my eyes peeled for deals and get parts as money and deals become available. Can I use the existing 32t middle chainring thats on the bike currently and just remove the 22t, and replace the 44t chainring with a bashguard and call that good? Or is there more to it than that?

    for the rear thinking about going
    -Sunrace csmx8-eaz (11-46) 11 speed cassette
    -Shimano RD-M8000-GS rear derailleur
    -Shimano SL-M8000-R shifter

    Is there anything else I would need to go 1x11 while utilizing the current middle chainring and going with Sunrace and Shimano XT components in the rear?

    Just got a DD10

    I LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!! I used to road bike only, but now i only want to ride in the woods! It's a great workout and it is so much fun!!!

    I am however wanting to go tubeless. Has anyone done this with the stock rims successfully? If so I'd love to hear.

    Congrats on the purchase, I'm new to it as well and its definitely addicting.

    I'm unsure about tubeless on the stock rims. I guess it depends on what year it is and accuracy of info i've read. The earlier model DD's we're considered not tubeless ready, but I've heard reports of people saying they've updated the rims either this year or last year and they're tubeless ready. I cannot give a definitive answer so you'll have to do more digging or bite the bullet and give it a shot...or wait for someone to confirm or deny.

    Many thanks!

    So i just got my DD10 converted tubeless by a local bike shop. I rode about 30 miles so far tubeless and so far...no issues at all. Reading that ppl were having issues with tubeless scared me a bit, but I just went for it. My bike is at 29 lbs currently and I just love riding this thing!

    I will say that the shop that did the tubeless conversion said they used Gorilla tape first and then used rim tape. They said the way they did it the Gorilla tape won't leave a residue behind though. 4 oz of Orange Seal as well in each tire. I'm not running a super low psi though. I think currently I'm running 14 psi.

    I have a set of OEM wheels off an '18 DD70 (no cut outs), they set up easily with a wrap of Whisky tubeless tape and 4 oz of Stan's. The rims are pinned so I had some air leaking from the seam initially but it sealed up quickly and haven't lost any air since. I've been running them for a month now with no air loss, impressed so far.

    I told a buddy of mine that i Felt (see what i did there haha) like i was i heard air loss while i was riding, but now i don't hear it anymore. In my case it could be the same as what you experienced. No air loss since here either. Loving it!!!

    DD70 FSA crown race

    The Felt DD Thread - DD70, DD30 and DD10-20190217_114031.jpg
    Hi,
    I would like to fit a Bluto and buy a new crown race instead of a complete headset. Can anyone advise which fsa headset is fitted. I intend to swop fork back again if I go bike packing. I don't intend to go bigger than the stock jumbo jims so I think the Bluto is an good choice for my ride experience.

    Thanks

    peter

    Hi, the crown race will be the same, but the external bottom headset cup builds about 10mm compared to the internal one meant for suspension forks, so the geometry will change a bit, but fitment should be fine. Not sure how much you will notice.

    Felt DD70 fork change

    The Felt DD Thread - DD70, DD30 and DD10-dd70-1.jpg

    Here,s my boy. had to expose in a photo editor with a filter to reduce the file size. It dwarf,s my old scott scale 26er. taking into account perspective the standover is marginally taller. No problem with the front brake... just had to turn the felt bracket the right way up!
    happy days.

    I'm looking to pick up a 2017 felt DD30 that's in fantastic shape. I love the color of these bikes. I've tried a couple other brands out and have been fitted as a medium frame. I am a little concerned about standover though as felts medium is 18.5" and most other frames run 16"-17.5' that i have seen. I am 5'10 i do have long legs. I am just concerned to buy the bike and have it shipped in and find i can't stand over the upper bar. I contacted Felt and haven't heard back.

    I am 5'10 (179cm) and I had this bike in medium, it is no problem with standover I was wondering if I should have gone for the small, but I think the bike would have become too short. I now have a medium Ice Cream Truck which is 18", but the standover is actually 779.2 compared to felts 775.

    I don't think you will have a problem.

    Wanted to put this here just in case it might help someone else. Sorry its so long

    I have a small frame '17 DD70, due to being a size small and the geometry of the frame I had a lot of trouble finding a frame bag that would fit the small space available. I had drawn the frame geometry per FELT's specs in autocad, scaled and overlaid an image of the bike, then started looking at frame bags and drawing them and laying it out. This allowed me to rule out MANY bags in a short period of time without having to spend 1 dollar. The ONLY bag I found that fit as if it was made for a small frame Felt DD was the Topeak Midloader 3L. Its not a full frame bag but it fits like a glove under the top tube. Short of making a custom one, this was my best option. I allows me to carry my repair kit, tools, and my Lezyne Micro Floor Drive XL Pump, with a little room to spare. Perfect for my needs.

    I also went from 3x9 to 1X11. I was able lose a little weight (around 525g) and free up handlebar space by removing the front shifter, front derailleur, replace all 3 chain rings with 1 and upgrade my other components. Here's a list of the parts I used and a couple notes

    Rear Shifter - Shimano SL-M8000-R XT Rapidfire Plus 11sp shifter Right Side
    Rear Derailleur - Shimano RD-M8000-GS Shadow RD+ Medium Cage
    Cassette - Sunrace CSMX8-EAZ-O 11sp wide range 11-46t Black Finish
    Chain - KMC X11.93 11sp Chain Nickel Finish
    Chainring - Absolute Black Oval 4x104/64mm 32t Black Finish

    All upgraded parts were brand new and everything went on without a hitch, just take your time and find a few good youtube videos to follow. I already had some of the tools needed (chain whip, Park FR-5 cassette removal tool, and chain breaker tool) but needed to purchase a crank puller for the chainring portion so I purchased a Park Tool CWP-7 Compact Crank Puller. Having these specific tools made the job SUPER easy, they're not absolutely required but HIGHLY recommended as without them, there's a good chance you will mess something up (just get them).

    I was going to replace the chainring anyway to get a narrow wide one so I went with the oval out of curiosity and cant see a downside as of yet, I'm happy. Going with this specific oval chainring, I didnt need to get different length bolts or need to use shims, direct mount with the stock hardware without issue.

    Found contradicting info on this but the medium cage derailleur works fine and shifts like butter with the 11-46t 11sp cassette, no need for the long cage version.

    I went with the Sunrace cassette vs the Shimano equivalent solely for cost reasons, it cost me roughly 30 grams in weight savings but I also got it in black which IMHO looks better than the silver.

    If you've never adjusted a rear derailleur, find a good video on youtube and follow it to a T. Take your time and it will shift amazingly once it's properly set up. If you mess up, just start over and go over the steps again. This was my first time and I had to do that. Took a little time but in the end it shifts great and I can say I did it all myself, it made me more knowledgeable about my bike and the process of assembly and adjusting for the future.

    Don't be afraid to try this yourself even if it's your first time. youtube and patience is your friend!

    Anyone crammed a 34t oval in yet? Just curious if it fits ok on a 3" chainline. By my measurements it looks real tight.

    For the record, I put a 34t round cinch chainring with a standard 6mm offset on a RF turbine crank onto the Felt DD and it fits with room to spare. I'd hazard a gues that a 36 might fit too. Chainline is a tad off center towards the outside but I ride the smaller cogs mostly anyway so all good.

    Two questions almost related.

    Is anyone here experiencing rotor flex when turning? If so, is it with the original fork or a a suspension fork?

    Anyone noticed play in their headset that is hard (or impossible) to get rid of without loading the headset bearings too much? Especially with a replacement fork. It seems the taper length of the steerer tube is not a standardized size

    hi guys, i managed to pick up a brand new Felt DD30 frame at a knock down price of £120 posted so couldnt resist so decided to build it up for the mrs!

    im not sure though which headset i need for it & also which bearings for the headset (or do all the fittings come with the headset?) ..ive pretty much built my own DD fatty from ground up, but ive never fit/replaced a headset!

    Any info much appreciated! cheers

    everything comes with the headset yes, it even includes the crown race which you press on the fork

    you can measure the inside of the frame with a caliper to know the dimension of the headset you need i.e. inside diameter up and down as well as possible length of each cup (which you press in)

    I do not know the dimensions so I can't help you there

    otherwise contact felt for information

    Is it a QR fork? If so, that is probably the source of the issue, although with the massive amount of rotational mass and gyroscopic precession, even 15mm axle is probably not appropriate for a fat-bike at speed. They probably need to go to 20mm. I've experienced rotor flex and this most certainly a problem, although it doesn't manifest in every situation. A wider axle is inherently fliexier due to longer lever arm across the same diameter, add the massiveness of a fat-rim and tire and it's a recipe for flex.

    It's a 15x150 axle. I replaced the original fork with a lauf fork but it keeps on flexing. The new fork comes with a new axle which I would have hoped was stiffer but have no proof of it either way. The only thing that hasn't changed is the wheel itself and obviously the hub.

    I've ridden a Cube Nütrail (several actually) which features a Bluto fork and Sun Ringle Mulefut wheels (with 4.4" jumbo jim) and 15 mm axle , no rotor flex there so now that I think about it means I can start blaming the wheels/hubs

    I guess that any 12x197 thru axle will work as long as it has a conical or flat washer, I'm guessing you need one with a flat washer.

    https://r2-bike.com/ROCK-SHOX-Thru-A...197-mm-FATBIKE

    Would this one work ?

    My bad, I assumed the rear axle had a flat washer.

    In that case, this one might work.

    yeh i seen that one but it says length is 232mm & thread length is 17mm

    The Felt one is 218 length so im guessing the syntace one would be too long?

    just an update, i managed to find an axle: https://www.syntace.com/en_GB/produc...UnI5WFLgNm5rtE

    Its very similar to the one you posted bjsoep except this one is 220mm in length!

    Some parts have arrived in post now, rest of the parts should be with me by middle of next week except for the wheels as these are the DT Swiss 710's being custom built will start a new thread when i start the build \o/

    I haven't measured the spacing but with the standard 160 mm rotor the clearance wasn't an issue but when I tried fitting an 180 mm rotor I found that to be more or less impossible due to the rotor grinding the pads more or less.

    This was on an 2016 DD70 frame, don't know whether that is the same design as the frame you're building.

    Hi im hoping to fit my burley trailer hitch to a used dd70 that is on its way . Super happy ! Is it as simple as buying a slightly7mm) longer back thru axel. So 204 mm roughly? What kind of tolerances are ok here ? Thanks


    and if these pictures work ok can any one identify what is on the back axel ?

    Is that a picture of the bike you bought or just an example? the picture looks like it already has a compatible axle. Not sure what kind of Burley trailer you have but if its like a kid trailer in that it mounts to 1 side like most kid trailers, the best option would be going with a Robert Axle Project axle (I believe the part number is KID215), I'm not aware of any other option. I used one for a kid trailer on mine and it was perfect to haul everything for a remote beach camping trip. I've since gotten a bob trailer which required a new axle to mount it since its very specific, and am selling my kid trailer and my 1st Robert Axle Project axle.

    If the bike you bought does not include a compatible axle and you'd be interested in purchasing mine, I plan to put it up for sale this weekend.

    Not that anyone has been clamoring for it but since my last update...

    -I've added a dropper post, a Brand-X ascend 100mm travel I got on sale for $85 from Wiggle, it works awesome and cant imagine riding without one now.
    -I have installed the 100mm bluto and it changes the bike so much (in a great way), I want to bump it up to 120mm but that will come later
    -I got a cheap 29+ wheelset to use on pavement rides. They're Framed 29+ Pro-X wheels and WTB Ranger TCS Fast Rolling 29X3.0 tires
    -I picked up a used bob ibex trailer, stripped it down, welded on new brackets for the upper shock mount, replaced the stock spring shock with an old rockshox air shock so its much more adjustable and smooth, and painted it satin black. Brainstorming on a rigid fender design that will allow panniers

    I'm loving this bike in both fat and plus configurations so much, I may not get an SN04 frame, just add TRP Spykes and call it good. Any questions feel free to ask

    Is that an internally routed dropper post? If so, did you route the cable through the bottom bracket junction? Additionally if so, are you using the sleeve on the bottom bracket?

    It is the internally routed version. I didn't run it through the BB, I just drilled the frame. I know some are completely against that but I'm not, in this case at least. It's a fairly small diameter (6mm) that I filed at an angle so the cable would lay closer to the frame. It also allows for a shallower bend than through the BB. Since I got rid of the front derailleur I ran it through the downtube
