    Fatboy Upgrade/Picture Thread

    I hope that this hasn't already been done, I searched and didn't see one dedicated to upgrading the Specialized Fatboy. The plan is to post your build/modification specs with weigh and pictures. Here's mine:

    2014 Specialized Fatboy Expert, 17.5
    Upgrades:
    *Both Tires setup tubeless
    *Ashima Air-Rotor discs 180 front/160 rear
    *Formula R1 brakes
    *Ritchey WCS stem 90mm
    *S-Works carbon handlebars, 635mm wide
    *S-Works carbon seatpost
    *Specialized Grappler XL grips
    *Specialized Phenom Ti saddle, 143mm wide
    *SRAM X9 trigger shifter, right side only
    *1x10 conversion includes:
    Raceface Next SL crankset, 175mm
    Raceface narrow/wide chainring, 32T
    Wolftooth 42T GC, red
    SRAM XX cassette, 36-12
    SRAM 1090 hollow pin chain
    Raceface PF30 bottom bracket
    *Shimano SPD 520 pedals
    *Specialized Manta bottle cage

    Notes: *Bike as shown weighs 27.4 lbs
    *With the Husker Du tires I have in the garage, the bike weighs 27 lbs. but I don't like the ride of the HuDu's. I feel that they self steer too much. In order to eliminate the self steer, I've had to use more air pressure, resulting in a harsh ride. I have elected to run the Ground Controls full-time because they are a smoother ride (to me) and I love the traction.
    *I run the SPD 520's on all my bikes. I've had major issues with the XTR version and decided that reliability is more important than nano-grams. Same is said for my seatpost, stem and bar selection. I've had weight-weenie stuff on the Fatboy and had failures. You can't win if you can't finsih.
    *The only additional upgrade that I plan to make is to add a set of HED Big Deal wheels.....hopefully before Iceman!

    I run clipless.....unless you mean platforms. I believe that there is a pretty good mix of clipless users and platform users in the fatbike community.

    Here's my current set up. After trying to find a current picture it really hit me just how much I've changed on this bike.

    This is the summer set up, we'll see how much it changes for winter:
    Left grip - ODI after removing the front derailleur and shifter
    Specialized Command Post dropper - this will get changed to a Reverb shortly
    30T N/W Raceface ring
    Salsa stem with rise
    Riser carbon bars (forget the brand, but fairly generic)
    Bluto (100mm) by far the biggest and best change to the bike
    Salsa 150mm front hub
    New spokes to go with the new front wheel
    On One Floater tires set up split tube tubeless - pretty much flawless in operation - I only put on the Floaters because I didn't want to wear out the Ground Controls in the dirt

    Stupid fun bike that has taught me a lot about riding, it really has reinvigorated my riding (as new bikes often do).

    PDW Mudshovel.

    Only updates on my bike so far was to have the shop toss the gripshift in favor of x7 triggers before I picked it up.

    Was going to go with DLX brakes, but they've been on back order, so the LBS is upgrading my to XT's for the same price - dropping it off today for them to put them on. And since I paid for the brakes when I bought the bike, no labor charge, w00t!
    Oh noes. I'm going to drink the Kool-Aid.

    Did you wear out your GC tires? Curious how many miles in what type of terrain? I'm itching to put mine back on, trying to wait until the snow flies.

    Anyone swapped out the original fit (overly heavy) tubes for lightweight ones?

    Any feedback welcome

    I tried lightweight tubes and pinch flatted at low PSI. I have found split tube tubeless to be much more effective. I've had no flats all summer.

    Thanks, yes have been through your threads, and endeavours

    Is the fat tubeless advantage worth it for improved ride would you say (flats aside)?

    I was considering giving the tape method a shot, but with the success stories in the Fatboy tubeless thread and talking to my LBS, I'm definitely doing split-tube. They gave tape a couple of tries but ended up going split tube and have done a few Fatboys like this.

    So I grabbed some of the 24" tubes and orange seal and will be setting that up when they give me the Fatboy bake with XT brakes.

    I also be doing my wife's Pug with tape, not split-tube....but that's another thread.

    Digital camo for the rim strips =D

    Pictures to come.
    Oh noes. I'm going to drink the Kool-Aid.

    After saving weight and preventing flats I stopped looking for other reasons to go tubeless. Some say it rides better, not sure I feel that.

    Yeah, I always go tubeless, and did so using Gorilla Tape on a Rabbit Hole rim a few weeks back on another bike with no issues. The Tape does fit 'exactly' into the internal width of the Rabbit Hole rim though

    I suppose the biggest rub is the weight of the supplied Spesh tube (Which Spesh says 'came out heavier than expected' although that may have changed)

    I did and really didn't have any problems unless you consider punctures related to the thin walled tubes. Last winter we had the best crust riding in a long time and I found myself getting into some crazy places and picked up a few thorns so punctured the rear twice. The front held out until two weeks ago and I forgot to check air pressure before riding and was too lazy to stop and deal with it when I felt it soft. Of course that's when I pinched.

    I probably won't bother going back to Q Lites because the Bontrager tubes have been good so far and aren't that much heavier.


    No current pics but -
    Bennies pedals
    EC70 2" rise bar
    Ergon grips
    XO (grip) shifters
    SRAM Guide RSC brakes (awesome!)

    I'm using Specialized 26" x 2.3-3.0". They aren't super light, but I still dropped a solid pound of combined rotating weight.

    My Upgrades:
    • Easton Carbon EC70 Seatpost
    • Specialized 90mm Stem
    • SRAM X7 Trigger Shifts & Foam Grips
    • Surly 64mm Wide Orange Rim Strips

    dude, just put the gc's back.. unless you have a tire preference or don't like the tire, i don't understand why you need to put different tires just so you can save your gc's.. you don't know what your'e missing trying to save your tires because you don't want them to wear out.. remember, yesterdays history, tomorrows a mystery and today's a gift.. that's why it's called "present".. so put the gc's back, and ride the s**t out of those tires.. while you are able to.. just buy an extra set..

    First proper ride on the GC's (and Fat Boy) today on my usual trails, which are mainly woodsy and hilly...

    Grip levels are off the scale

    Especially cornering, but braking and climbing are ridiculous also

    I didn't get near the limit on cornering, but I was laughing out loud on a few occasions, thinking I must trust them more and more

    I'm still playing with PSi though

    I did slip once on a wet root which I rolled over on a sloped angle. I think the tyre's smooth bit, in between the knobs contacted it, so it had nothing to bite on. The tyre (front) slid down and then gripped on some different stuff

    If the Floaters were a letdown, the GCs would be on the bike in a heartbeat. Likewise if the GCs weren't $160 a tire, I wouldn't be riding the Floaters at all. I gotta make this biking thing work from a cost perspective.

    Yup, I did...my bike didn't make it off the showroom floor with the original tubes or platform pedals. My experience with tubes was, why? Setting up tubeless was pretty easy, I lost a ton of weight and have not had any issues with the tubeless setup on the fatboy. I say go for it. If you'd like to know my process for setting up tubeless, let me know.

    yeah, they are expensive but that's not gonna stop me from riding these tires.. a couple of dollars a week, and before you know it, you have enough for one tire.. your set of floaters could have paid for one gc.. then just save for the other.. gc's would last you long enough that by the time they are worn out, you have saved enough for another set.. and then the cycle goes again.. tires get worn out... but your bike.. so, your call..

    Went tubeless today, just picked it up the other day from the LBS after they put the XT's on. (Ice tech rotors en route)

    Used some digital camo gun wrap for the rim strip, 24x2.25 split tube. Aired up fine with the hand pump and haven't leaked any orange seal yet. Took the air pressure way down and couldn't burp it, so I think it should be good.

    Other than that and the x7 triggers, its all stock. No issues with the cranks so far.

    Sorry for the slow reply. I started by taking the tire off the wheel and wiping the rim down with alcohol. The higher the alcohol content the better because it does not contain additives that create residue. For tape, I used some plastic tape that I bought at a warehouse, no label, but it has a sticker that says "Part No. Y65256". I've scoured the internet to find a source to no avail....It's 3" wide and Fatboy Expert "Red"...a bonus. I started by putting the first layer down the middle over the factory rim strip, making sure it was stuck well. Then a layer on each side, making sure to put tape up on the rim sidewall (this is especially important with HuDU tires". Make sure that both the side strips of tape seal well on the center piece, assemble the tire with the factory tube to 20 psi and let sit for at least one hour. Un-seat only one side of the tire and carefully remove the tube and install the tubeless valve stem. Put in two scoops of your favorite sealant, soap the tire up with alot of soap and place the tire horizontal with the 'loose' side hanging down (gravity is your friend). Attach an aircompressor and it should seal. One issue that some people have with leaking tubeless setups is the though of using high pressure to seal. I NEVER exceed 10 psi with my setups, it stresses the tape and creates leak paths, plus I like the lower pressure for racing anyway. A little tip that I have is, I use three milkcrates tie wrapped together as my tire mounting station.....I'll post a pic if needed.

    Here's my guy. I haven't upgraded or changed too much yet. Just added on a quick clip-on rack and we've been fabbing up a frame to build a rear fender with.

    Sounds like other brands of tires, besides the GC's, will fit on the Fatboy rims...such as HuDu's and D8's...is this correct?

    @ jack - thanks for posting that.

    Sounds pretty much identical to what I have done, except I used 50mm Gorilla Tape.

    Three strips (minus the rim strip, so straight onto the rim) first middle one facing up, then other tow each side. More of what I did here

    I like what you say about keeping psi low. I did go to 20 while soap leak testing, but will keep that lower in future

    5 rides on the tubeless now and it's held

    Cheers

    There are plenty of people who have been successful with Gorilla tape, I am not one. Other than to seat the bead I never had my tires over 10PSI, but the Stans still got under the tape - I didn't do the middle strip upside down thing though.

    Got mine last thursday and have swapped the handlebar, seatpost and stem for highend ritchey parts, brakes to slx, saddle to a slr carbon and the rim strips to the blue surly.
    As in picture it weighs 14kgs.
    Waiting for the speci xd drive body then will swap the back end to a xo1 cassette and derailleur with a xo1 gripshift and a raceface blue 30t chainring up front on the original crank.
    After reading the horror stories this morning about said crank i checked mine and it was fine so applied more than enough copper paste and did it up again to 34nm which seem alright, not sure what is supposed to be. when i change the chainring i will pull the lot off and repack the bearings with a good grease and copper paste the rest.
    Future plans after that lot will be hope hubs and a rs bluto fork, but after the princess gives the go ahead, not scared just smart
    I maybe getting older but i refuse to grow up!

    Yup. Using the Specialized 26 x 2.3 - 3.0 tubes. Dropped almost a pound per wheel. No problems whatsoever. Running anywhere between 4# and 12# pressure, depending on application. Summertime riding everything from commuting on pavement, to xc rides through roots and rocks with tech climbs, to AM/DH type stuff ripping through baby heads and roots, with small (under 3') drops and jumps thrown in for good measure. I did try squaring off a turn in a berm (7 psi at the time) and the tire did move and had a bit of a wiggle in the tread for the rest of the ride. Got home, deflated the tire, aired it back up and the tread is straight again. I am 5'11" and 175#, ride aggressively, especially considering what the Fatboy was actually designed for.

    Just learn to ride smooth. If you plow through stuff with disregard for line, and expect the bike to save you, then you'll probably get pinch flats with tubes.

    Yup, I've mounted and ran HuDu's on my stock rims….and they were setup tubeless. After 16 miles I went back to the GC's….they ride much better at race speeds.

    I am replacing the Command Post with a Reverb (I like the infinite stop aspect of the Reverb). This remote does not play nice with the brakes on the Expert Fatboy! Either my brake lever or my Reverb remote is going to be out of position (I always have run my dropper remote on the right side). I think a left upside down would be in the wrong spot too. Ugh, sucko, I guess new brakes are next on the list :-D

    I did the tubeless thing with the Scotch transparant tape . Worked really well , no leaks or losing air. No upgrades yet besides going tubeless . Did swap the spacers for a carbon one

    Ok boys...lots of great rigs on this thread. As an update to the capabilities of this bike, this past weekend I won the CAT 2 50+ OMBC Championship round at Mohican State Park. I was the only fatbike in the class and beat some pretty good Ohio riders. This is turning into my favorite bike! For reference, the race was 27 miles, 3900 ft of climbing and I did it in 2 hours, 26 minutes.

    Nice bike- glad you mentioned the Dillingers, reminded me to swing by my LBS yesterday. They had just got a shipment in and I picked up a pair of 5's.

    Stephen....Agreed, the 'motor' has a lot to do with it. My point was, that this bike is a very capable XC racer. I absolutely love this bike.....my back up is an S-Works Epic 29er :-)

    Looks great! I am on the fence pro vs. expert. I am leaning Expert as I don't need the dropper. How do you like the wolf tooth?

    The wolftooth has been very good....I have it on two bikes. While it's not shimano buttery smoove....considering that it goes from 36 to 42 teeth, it is very good.

    Nice. The paddles down the center look like they'll move snow well. The side lugs are well supported and look like they'll dig too. The round hollow studs are supposed to provide more surface area for grip on ice. Can't wait to give them a try in the snow. The rubber seems soft, so I don't wanna run them in the plus 15C to 20C we've been getting here lately. I know that keeping edges and sipes fresh is critical to snow/ice grip.


    I found the Dillinger 5's are narrower and shorter than the Ground Controls, the Bud and Lou, and the Snowshoe XL. I don't mind this as I want float, but I also don't want to be pushing against so much snow (because of more width) in fresh conditions (you'd be surprised how fast the resistance builds when you're trying to plow through deep fresh on super wide tires), that it bogs me down. I think the Dillinger 5 fills the spot nicely.

    On a side note, Specialized hit it out of the park with the Ground Controls for a summer tire. Little to zero self steer at any pressure above about 4 psi. Great grip like a billy goat on the climbs, that sheds debris, rails corners, and is stable through chuck and chunder. Although they could definitely fit tighter on the rim. Squared off a corner coming out of a burm and put a significant wiggle in the rubber as it moved on the rim...at 7 psi. Now running about 10 psi to keep the tire in place.

    Can't wait to try out the Dillinger's in the snow either! I was debating between these and a Bud/Lou combo, but I wanted studs for some grip on all the ice that seems to build up by mid winter. Studding Bud/Lou's seemed like it would make a heavy tire even heavier and would cost more for less studs. I'm hoping the Dillinger 5's make for a nice all around winter tire.

    I finally had to swap my grip shifters for x9 triggers, too. I put on some ergonomic grips also and comfort has vastly approved.

    Hello!

    My 2015 Fatboy I designed, as you can see it on the pictures.

    -other finish
    -800mm wide handlebar with short stem
    -Brooks saddle (very convenient!)
    -Lefty
    -bottle holder
    -Bell by Crane-Japan (beautiful sound!)
    -Conversion to only one chainring (30T race face)
    -rear 10x cassette 11-42 (e * thirteen 42T)
    -"Suicide circuit" at the seat clamp (silver without grid)

    Coming Soon: BMX crank (KHE Hindenburg) and Magura MT5 200mm f / r

    I hope you like it. I am very satisfied. It goes better with the changes for my needs a lot. particularly lefty, wide handlebars and stem are short pleasant.

    Dear greetings from Germany!

    Fork -- 80 mm Bluto
    FSA headset
    90 mm stem replace 60 mm stock
    Front wheel -- 150 mm hub to fit Bluto, with Clownshoe rim
    Cassette -- 11-36 XT, but with 42 tooth Wolf cog

    Thank you for your feedback signal. I hope you like it. I think so in about 2 months I'll be ready with the tag. Unfortunately, there is always a very expensive hobby, but it's incredibly fun and joy!

    See the previous page for the pictures. Here's the stuff....its -just- wide enough for the fatboy rims if you take care.

    Thought the GCs were big and narly. Replaced the rear with a Lou. Holy cow - it makes the GCs look wimpy. Really big with huge lugs. Fits fine, but barely.

    Wild guess, Bluto is about 3.5 pounds and stock carbon fork is 2 pounds?

    Jackdz my frame just came in build starts next week. Bluto has been ordered. Do you still have your front derailleur mounting hardware?

    My build is going to be mostly xt with xtr brakes. If I love it then HED's next year....

    I think the Bluto adds 2 pounds. But you shave that off with HED's, right? I tested the Fatboy with the Bluto and w/o. I was hitting stuff with more speed and not being bounced off the pedals with the Bluto. Felt like when I got my first Rock Shox way back in the mid 90's.

    CHSAD, Yeah, I still have all the front derailleur hardware…I'm still skeptical on the Bluto…I really like the 'flick-a-bility" of the lightweight build….but my old man wrists do feel it.

    Well I was thinking lightweight at first but I have my epic for that. I noticed the rigid fork in my shoulders at first. It will be nice to still have the rigid fork if I want to go that way.

    If you get a chance can you shoot a pic of the hardware for the front der? I am going to have source it as the frameset doesn't come with it.

    The tightest clearance is the chain/tire. In low gear, there is about 1 mm clearance, but it works.

    I heard there is a way to use the existing hub by adding some spacers and different bearings. Here's what I found

    That looks easier than buying a new hub and relacing a wheel.... Where did you find that guide?

    Hmm, the wheel was pretty easy to build, think I'd rather do that than that conversion, but that's just me

    I'm with you. That "conversion" looks like a problem waiting to happen.
    Oh noes. I'm going to drink the Kool-Aid.

    I am waiting for the next shipment of fatboy into Australia and am tossing up between the fatboy and the expert. Considering I would make a few upgrades fairly promptly, the 1st bein Xt brakes, I am leaning towards the standard fatboy in the orange( to match my 1997 S works) I have some 690mm carbon bars, are these considered wide enough for a fatboy? will try the std seat but I love Flite saddles so one will go on. XT spd's and will attempt tubeless if I can get rim tape suitable.
    This will be my 1st fat bike and am looking forward to low tide runs on my local beaches, can go 10km in one direction and 8km in the other. Any tips for a newby will be appreciated.

    Welcome aboard the fat bike train! I think you have a solid plan for your bike. I started with the Expert, but the only thing left is the frame, fork and wheels. I would have been better off buying the frame and building it right the first time.

    As for the handlebar question, check out this thread:

    I usually run 8psi or so for general off road riding. Much more and it gets too bouncy. Less and I worry about pinch flats and/or denting a rim.

    Mods so far on my Fatboy Expert:

    tubeless - 3M tape w/ Orange Seal - the best mod, by far
    Easton EC70 720 mm carbon bar
    Easton EA70 70mm stem, 6 deg down
    Easton EA70 seatpost
    Ritchey WCS Marathon saddle

    and bought a 0-15 psi gauge, highly recommended

    ...looking for a set of studded tires for the winter, probably 45NRTH

    I have this one:

    Amazon.com : SKS Airchecker Digital Presta and Schrader Pressure Gauge : Bike Pack Accessories : Sports & Outdoors

    and this one:

    Tire Pressure Gage Schrader Presta Michelin MN 4606B Digital Bicycle Auto | eBay

    When using the Michelin, it's best to lubricate the end of the gauge as there is an o-ring that can pull out.

    Banged out 35km on the fatty this am. so much fun, lots of wooden stairs to access beach in my area. now have a great route going up the shallow ones a little allong the top path then down the longer sets, bit of rock/reef riding to get around a bluff. Am totally stocked with my expert. Will replace the grips with esi chunky's, tossing up whether to go with a set of RXL carbon bars I have that are 700mm, so a bit narrower.

    My LBS told me not worth going tubeless on fatboy as bead does not hold well on low tire pressure. I want to go tubeless for weight and flat sealant. What experiences have you guys had?

    I've been tubeless on my Fatboy since February of last year. I burped air exactly once when I was riding sub 5PSI. In my experience the Fatboy rims are excellent for going tubeless. I used split tube, after several failures of gorilla tape, but people have been successful with tape and other solutions.

    Just a question for all fatboy riders

    How high/low do you run your bars in relation to your saddle height.

    After many yrs on rd and XC racing I tend to have mine a fair way below my seat. I guess it is going to be trial and error, I have a set of 700mm carbon flat bars I can throw on but wondering what you experienced fatties think.

    Is a wider riser bar an advantage? or should I run a similar width to my 29er race bike?

    If you set it up properly, tubeless works excellent on the Fatboy.

    I am running 1 layer of 3M Tough Transparent tape on the front with no problems. This tire has 4 oz. of Stans. I am running 1 thicker layer of Nashua UL Duct Tape on the rear (which is slightly heavier) with no problems. This tire has 4 oz. of Orange Seal.

    I typically run 6-7 psi, though I ran as low as 3.5 psi in testing.

    The biggest difficulty is sealing the seam of the rim. My rear wheel was more problematic in this regard, but I did get it with more tape overlap. You also have good coverage over your vent holes.

    As for bar stem, I swapped out the stock units for a flat carbon 720mm Easton bar and I'm running this with a neg 6 degree 70 mm EA70 stem. This puts my bars in a lower position more akin to that of an XC race bike. I am 5'8 running a Medium.

    Why heavier tape on rear, 3M not work? Also why stans front and orange rear?
    Is tape better then split tube?

    Stans or Orange, does it matter? Heard some say it eats thru duct tape, not sure about 3M.

    I like the Orange Seal better. Why? I think it seals leaks better and faster. I just think it is a slightly better product. As for eating through the tape, I have heard this too, but I have not had my setup going that long.

    The key to making the Fatboy work is to seal very carefully around the vent holes and th rim seams. This causes all of the problems. On my rear wheel, the seam was so poor that I resorted to taping all of the way up the vertical of the rim. This took a little more care with the tape, but it worked perfectly. If too much sealant gets into the seam, it works its way into the rim and then it undermines your tape job and everything goes to hell. I know because I failed on several tape jobs with my rear wheel.

    Posted this on another thread.. Anyway, my puller cap was lost on one of my rides and lbs ordered me a whole new crankset since they cannot just get the cap... Lo and behold specialized upgraded my crankset and sent an e.thirteen, the one the expert uses.. For free!!! Aesthetically, it looks way better than samox.. With all my upgrades so far, all i need to replace is my rear deurailler to xo and it's already an expert if not more.. Since i have bluto and xt brakes, 206mm f and 180 r, and reverb dropper seatpost..

    Just had to re do the rear after 6 weeks. The Stans had worked it's way under the tape and lifted it in places. That was with a 3 strip (of 50mm) arrangement

    Now put a 4th strip in the middle over the other 3, and left a tube in overnight in a warm room.

    The fluid has really got a long way to go now.

    Did you use the 3M duct tape or something else?

    Swapped out the std bars for a set of Bontrager RXL 690mm carbon bars which came off my Superfly, a garmin out front mount, a Thompson elite layback post and Flite carbonio.

    Good job!

    Single Ring 30T Blackspire narrow wide on the Fatboy Expert e*thirteen stock crank. I tried a direct mount e*thirteen ring, which looked super slick, but the chainline was not quite right at 66. This setup has a 72-73 mm chainline which is a better match for our 190 rear hub. It works flawlessly btw.

    I had brake problems, on the Expert, kept fouling up to the point of almost not working and shuddering-screeching. I think the problem was it came with sintered pads and the disks are rated for resin only.
    Running resin now, all good. The resin pads I put in definately look different to the original ones

    Anyone know the stem lengths on the FatBoys? I am about to land a FatBoy Pro and there are no marking on the stem, and nothing on Specialized's website. Size M is the one I am looking at, and it looks like a 50mm.

    Somebody asked why I preferred Orange Seal to Stans. I have one wheel set up with each. I popped the bead today and the Orange Seal was still liquid after a month. The Stans had this rubber booger, but it only weighed 4 grams, so I took it out, added a little more Stans and kept rolling.

    That's my beef with Stans. All the stuff that makes up the Stans Boogers is the stuff that is supposed to help clog up a puncture.

    At this point, I've had 2 punctures in as many years having gone tubeless. One with Stans in a Larry that just wouldn't seal. The Stans was around the same age as yours, opening the tire revealed a nice big booger. Spun the tire, tried riding, everything....it just kept spraying air and Stans.

    Had a nearly identical puncture a couple week on my wife's bike with Nates and Orange Seal. The Orange Seal was about 3 week old. It sealed right up within about 15 seconds and was good to go. Barely lost any air, either.

    We'll see how everything fares after winter, but so far, I'm happier with Orange Seal.
    Oh noes. I'm going to drink the Kool-Aid.

    I just bought a Fatboy Expert 2015 yesterday and went tubeless... Stock tubes were 470 grams each, red rimstrips 52g each.

    Replaced these with: 1 layer of 1.88 Gorilla tape upside down as the rimstrip, 3 layers of 50mm wide vapour barrier tape and 3 scoops of Stan's per tire.
    I applied the vapour barrier tape 2 layers to the edges and then 1 layer to center. With some stretching, It was very easy to apply without any wrinkles.

    Seems to work fine and rolls noticeably better with low psi, long term test results to follow... I didn't want to go the Gorilla tape way after reading bad long-term reviews.

    Looks good - let us know how if fairs longer term

    My Gorilla Tape only 3 strip method lasted 6 weeks

    Edit: currently on the Gorilla 4 strip: three strips as before with a 4th final one in the middle - went up straight away and has not leaked at all - yet - , which the 3 strip did

    Here's my long-term review: It was not a good idea. Vapour barrier tape doesn't like Stan's sealant at all, started leaking after 6 hours...

    Back to inner tubes and 600g more rotating mass...

    I've said it before (a couple of times) , use the Scotch Transparant Duct Tape . Mine holds air and doesn't leak for weeks now. And the wheels have gone through mud and water a couple of times.

    At the risk of being pinikety (things are sometimes lost in the typing) can I ask exactly how many weeks and what you mean by going through mud & water a couple of times

    Fatboy Upgrade/Picture Thread

    About 5 weeks now. What i meant was that my rims have been very wet , hubdeep river crossing , and the Scotch tape is still firmly attached to the rim/rimstrip.

    Fwiw...While I used split-tube on my Fatboy, I used Tyvek barrier tape on my wife's Pug w/ Rolling Darryls. Two strips, overlapping in the center. Put a tube in and let go overnight to set the tape.

    No leaks or any other issues over the last 3 months. Used Orange Seal.

    The BMX crank unit is now installed. This went very well and without problems. The 48 spline axle is 19mm and comes from PROFILE. The crank arms (also PROFILE) I have elected to 160mm. This I have more ground clearance and a narrower stance. For me very pleasantly.

    The PROFILE chainring has 25 teeth and is perfectly adequate for my strength & endurance. Only now do I use more often the smaller sprocket of the rear cassette.
    The pedals are now significantly more stringent and more than like the old plastic. They are SUPER STAR and fit in my opinion quite well with the rest.

    By chrome crank arms I have now permanently no more ugly abrasion.
    The holder and the cable routing from front derailleur I have now sawn off and repainted.

    My Ride


    Upgrades completed.
    BB7s - SD7s
    EC70 low rise carbon bar
    Thomson Setback seatpost
    WTB Pure V - It's what I like
    Redid the rear hub bearings.
    X7 trigger shifter - ditched the left
    32T Wolftooth Chainring
    Sram Cassette
    XT skewer ends on the stocks - it is lighter and easier to grab.
    BioKork Grips
    Tubeless with Pegasus tape - working very well.

    I may replace crankset with a the Next and direct mount 30T or do the 40t/16 in the rear. Unsure about that. I finger shifted to the 22 today for a climb and that was certainly the cheaper option. Just haven't gotten around to removing it yet.

    Fatboy in Boise

    Fatboy Upgrade/Picture Thread-img-20141114-00384.jpg

    Bought this Fatboy in July. Been waiting for snow ever since and slowly upgrading. I owned the Boise Greenbelt yesterday after an early season snowfall. Couldn't be happier with the Fatboy.

    UPGRADES
    RaceFace- Next carbon seat post, Next carbon bar, Speed V gel saddle (yes I realize this undid all the weight loss from the post, but I need it)

    Ritchey 32 degree 80 mm stem. I'm old, can't be bent over too much.

    1x10 conversion using Samox crank and a RF 104 BCD 30 tooth, narrow-wide chain ring. Will go with Next SL crank with 28 tooth direct mount if I can figure out which parts to order.

    Shimano XTR cassette (Ti cogs- huge weight loss)

    Q tubes, ESI grips, Xpedo pedals (279 gms total). Stuck with the gripshift. I have always liked them. The light is a cheap Cateye. I have a nice NiteRider 1200 lumen light, but it isn't dark enough yet on my commute to need it. I took too many links out of the chain when I went to 1x10 as is obvious in the photo. Gotta fix that. Any chain recommendations?

    Upgrades- not sure which to do. Brakes? XTs are better, but are they any lighter? I only ride snow at this point and do not need great brakes. Although the Tectros are pretty squeely when wet. Probably try a tubeless conversion. I think Fatboy may be under 27 pounds as is, for sure it's under 28 according to a not so accurate scale I have. I have wanted a real fatbike ever since my 2.4" snowcat rim days back in the 90s. 4.6" tires were unthinkable back then.

    Hi,

    Has anyone who's done the 30T Raceface Narrow/Wide had to buy the spacer shims or does it work without them? I'm going "1 x 10.5" with the OneUp 42T (+16T Cog) conversion kit and the Raceface 30T N/W upfront.

    Also for those folks who have done this, did you have to get a new chain or were the number of links good?

    Thanks in advance!

    I ran a 1x10 before I went full-on 1x11. Any of the 30T narrow wide front rings mounted on the oem crank will put the chainline near perect. (Technically it is off by 1-2 mm, but it is pretty close to the middle of the cassette.)

    On my medium, the bike came with 55 links. When I bumped up to 30-42, I needed 56 links for proper chain length.

    Whats involved in going XX1or XO1?
    Do you need a new rear hub or does the 11spd freewheel fit the std specialised hub?, I have the Fatboy Expert.
    Then it is cassette, rear mech and shifter plus a front ring.

    Are you sure about this? 55 links seems way too short. I'll count mine when I get home, but I bet its twice that.......

    Orange is the new phat

    Fatboy Pro

    The frame is Orange, because I needed a large so Hilltop, the LBS, swapped the Pro parts onto another FB frame (they are all the same).

    UPGRADES

    Tubeless-most important. Running 8lbs now without snow on the ground in NJ, but might reduce pressure depending on how they hook up in the white stuff. I weigh 200lbs.

    Thomson carbon bars-I'm 59 and want to reduce the harsh.

    Thomson elite seatpost-(downgrade that I swapped for the bars) Never had a dropper, but might put the Thomson or the Fox on another bike to try it.

    Selle Italia saddle-They fit my anatomy

    32.1 lbs with the Bluto is pretty good.

    One of my riding buddies said he will be buying me fenders after he got rooster tailed in the mud yesterday.

    Got my eighth ride in nine days of ownership. Hopefully, that is the ratio which we will maintain.

    I'm guessing he's just counting outer plates. If you ran a chain with an odd number of links you wouldn't be able to connect it.

    To clarify, 56 is the # of outer links including the quick connect.

    Spec makes an XDriver that fits our hubs for about $55.

    Got mine back from a warranty freehub replacement this weekend.

    Added 200 grip studs to my Bud and Lou's to see how they compare to the Dillinger 5's I've been running.

    Also added a set of Cobrafist's with Ergon GC1's, mud shovel fenders, and a Garmin 64s.

    Mostly stock otherwise, except for a XT cassette, and Glowworm XS.

    Thanks! It's smoke plexiglass I had laying around. Just cut out the shape on a band saw. The down tube fender I used a blow torch to heat and bend. I got the material from a store called tap plastics, hopefully they have one in your area.

    My digital scale which reads to the tenth of a pound put it exactly at 30lbs with pedals, 6oz of stans per wheel, and a little bit of today's trail dirt

    Do you need to use rim strip if you go split tube?
    Any reason not to trim excess tube?
    Any reason not to trim tube down to corner of inside side wall of rim. That seems to be the place the tape guys run tape to. Not up side wall.

    Went 1x10 with OneUp 42T and RaceFace N/W 30T

    I moved to the land of 1x10 with the OneUp 42T (+16T Cog) and an orange RaceFace N/W 30T up front. I like the cleaner look and I dropped almost a whole pound of weight...

    I am really enjoying this bike.

    You'll want to use some kind of rim strip to protect the tube.

    You don't have to trim, but may want to if it is rubbing.

    I trimmed down to the sidewall with a nice sharp blade by getting it started, pulling on the exposed cut tube, and sliding the knife, using the rim to guide. It was really easy and looks super clean now.

    As long as you use a tube that has a valve with a removable core you can add sealant without breaking the tire bead.
    Oh noes. I'm going to drink the Kool-Aid.

    Upgrades before leaving my LBS:
    Thomson Carbon Bar 750mm
    Race Face Atlas stem 65mm
    Swapped the black Bennies for white ones
    Swapped the black Z-Cage for a white one
    Swapped the dropper post lever to the shifter style lever (not pictured)
    Specialized Enduro Lock on grips same color as the frame, with blue lock rings (not pictured)

    Updates on the backlog:
