    Specialized Fatboy Accessories

    Hi Fat Bike Riders. I was hoping to start at thread dedicated to the Specialized Fatboy dealing with accessories for the Fatboy. More specifically front and rear racks, frame bags, panniers, seat bags, handle bar bags etc.

    Since this is the first time the Fatboy has been offered it may be difficult to order on-line or walk into our LBS and select items. It sure would be nice to have others tell us what has worked for them and what did not work so we are not reinventing the wheel each time.

    I, like many of you, am still waiting for my Fatboy to arrive. For those that have their bike already and have purchased accessories let's talk.

    What did you get and why? How much? Are you happy with it? What would you change if anything?

    Throw in some photos for sure. I look forward to seeing what fellow Fatboy riders are up to.

    After Lu-Max mentioned it in the ETA thread, my first accessory will be one of these for my expert.

    It looks like a bike shop. Perhaps they could tell you what it is or sell you one.

    I am guessing it is a Salsa.
    Salsa Cycles

    Edited to add Salsa link.
    I wanted to post a photo that Homer J posted under another thread. Back rack on a Fatboy. Click arrow by Homer J's name and it will bring you to the original post. Thanks Homer J for the picture.

    I spoke with the boys at Bike Barn Racing and the rack is a Salsa Alternator. Mounting modifications were necessary to make it fit the Fatboy - meaning they needed to use other parts from other racks to make the mounting work.

    Hopefully we will see dedicated racks for the Fatboy at some point.

    I was hoping to ask a favour from one of you lucky dogs that have your Fatboy already. I am looking to get a frame bag but my bike won't show until March. Can someone give me the inside dimensions of the front triangle for a MEDIUM Fatboy frame. At least I can start to look for a frame bag. I am looking at a Revelate Designs bag, amongst others, but I need some dimensions like the dimensions shown from their website or an idea of which size bag would fit on a medium.

    Thanks in advance.

    Specialized Fatboy Accessories

    I've had it for about 6 weeks and finally got the time to put some stuff on it.

    (And found a new use for my motorcycle lift table)


    Not much, but I'm content....
    Spank bars and pedals, a Rokform phone stem phone mount, water bottle cage and a seat bag.

    Haven't had much time on it but my only complaint is a kinda creaky bottom bracket

    Hi AZtransplant:

    Looks like a medium size frame. Nice setup. Love the colour match. What size rise on the bars? Did you change out the stem as well or is the rise in the bars sufficient to place you more upright?

    Thanks

    Thanks,
    It's actually a large frame. The bars are a 20mm rise (5* up & 8.5* back) and 62 mm wider. The stem is the original one. It feels a lot better to me and I'll leave it like this for a while and try it out

    Take a read on post #14 - I need the measurements of a Medium Fatboy Frame - front triangle.

    Has anyone else looked at a frame bag and/or seat bag that they are happy with????

    I will be doing a couple of 2-3 day bike trips and I want to get this sorted out for the two Fatboys I expect to have in several weeks (expect - that's a pretty big word).

    Finally I had time to measure my medium.

    I got the following
    A-17"
    B-1"
    C-18"
    D-3"
    E-10"

    The Cheap Ibera Frame Bags... The medium (12") bag fits the Fatboy small and the large (16") fits the medium Fatboy almost perfect.

    Thanks for the info NogginBuster. I will give Ibera a look.

    When you say the large Ibera bag fits a medium sized Fatboy would it fill the entire inside triangle? I would be looking for a frame bag that utilizes the most space within the front triangle.

    Thanks again.

    Initially, I just held the bag up next to the frame. It actually rests on the down tube. I think I'd prefer it not touch there.

    That's a nice fit. A little 3M clear protective film on rub points and she would be mint. Thanks for adding the photo. I think I just may go ahead and order one. For $20 CDN I don't think you can go wrong. Most reviews on this bag seem to be quite positive. As for touching, when I looked at the Revelate Design bags they all touch the down tube. Only difference is they have Velcro straps for the down tube where the Ibera does not. Most of the reviews I read didn't seem to think this was a problem. The bag stayed put. Thanks again.

    Also NogginBuster:

    I notice your Fatboy has Dillinger studded tires. Did you not like the Spec Ground Controls for winter riding? I suspect the studded tires must have some crazy grip on ice.

    Nice job on the rim strips- great colour match.

    I tried the Old Man Mountain Phat Sherpa It looks snug but there is no point on the rack that is closer to the tire than the frame and the front derailleur get. The only issues I had is that the wheel isnt quite centered so the left extender got closer to the tire than I was comfortable with. I ended up using a small spacer with a longer bolt on that side. I am happy with it.

    I like the rim strips. What width are they? I like your handle bars as well. I must say I have never seen a bar setup like that before . Your ride looks good.

    I used the rainbow "duck tape". I am not sure what the actual width is I think it was the 1.88in. The bars are the Jones Loop bars. I didnt like them on my other bike but they seem to be a good match for the Fatboy.

    What I went with on my Pugsley. It is a stout rack. The very next day after I received the rack and mounted it I rode to meet up with a couple friends for a ride. Unfortunately on the way to the meeting place I hit a large patch of black ice over fairly new asphalt parking lot and wiped out. The entrance was covered in ice that wasn't visible and it was sloped downward. I braked to slow my speed .. not even 50 feet to where we meet up and my bike suddenly flew from underneath me. The rack saved it from any damage which was apparent from the long, deep scrape on the rack. I didn't fare as well .. healing from a fractured pelvis. That happened five weeks ago and I can't wait till I can get back on. Did I say that I highly recommend the OMM Phatt Rack? Oh yeah .. it serves more than one purpose than hauling stuff. It can prevent your derailleur and frame from taking a bad hit.

    Can't really comment much on the Ground Controls, only a few spins around the yard. We've had plenty of snow and ice and snow and ice and on and on... Put the Dillingers on just because of the ice factor. No complaints on the Dillingers so far.

    Fantastic setup! Did you have to modify the mounting hardware at all, specifically the bar that connects to the top of the seat stay? (Ie. bend them over).

    Also what type of grips are those? Do any aftermarket grips work with the twist shift? Apologies for the dumb questions.

    I had to bend them a little. I think I would have been better off using spacers on both sides instead of just the left since I ended up taking a chunk paint off the frame when I was figuring out how much they needed to bend or if I was going to have to twist them. But that also could have been avoided if I had planned ahead.

    The grips are ESI chunky. They line up really well with the twist shifters. I did have to cut them shorter since they only come in full length but they are easy to cut and I like being able to choose how long I wanted them.

    Specialized Fatboy Accessories

    Anyone else care to show what they have done to their Fatboy? I've gotten some great ideas browsing through some of the threads, but would be interested in seeing some more...even if it's homemade (sometimes those are the best).

    For those running a top tube bag (aka tank bag) which ones fit best? I've noticed that most have a velcro attachment that is quite high, and the stem is quite low on the bike. Also on the medium and small frames, the top tube and down tube converge and may prevent velcro attachment underneath (towards the front).

    Has anyone put a bashguard on a Fatboy? I hit my ring on a rock during the last ride and it made me cringe thinking of summer riding.

    I don't think you can (I could be wrong). I was looking at the MRP products and the fatboy does not have the brackets to enable one to mount it.

    20mm Riser Bars and tubes

    I felt the need to replace the handlebar only because the brake levers hit the top tube. I plan on falling frequently next winter and I didn't want to dent the top tube. I now see that Lu-Max has the 40mm riser bar. I am sort of wishing I would have got that instead.

    I have a large Fatboy frame and I am curious to see if anyone has fit the Large IBERA frame bag on it. I would think from NogginBuster's post that a large bag should have no problems fitting nicely within the triangle of a large Fatboy.

    If anything it's probably a bit small for a large frame.



    It's a better fit in my large Superfly frame.

    Lewy - thanks for the reply. Definitely a bit on the smaller side. Funny, I didn't think the triangle on the large size FatBoy looked that big. Nice pics as well.

    Got the OMM Phat rack where I wanted it to be. I believe OMM may be updating their "Fatboy" package. What you see mounted below is longer lower brackets, and slightly longer support arms to accommodate the added height. With this setup, it allows the mounting of a mud shovel underneath.

    Good news and bad news on the BBG bashguard. I ordered the 34T version of this one:

    It fits perfectly on the crank with some longer bolts.

    The bad news is it doesn't clear the front derailleur. It misses by a very small (maybe 1/16"), I need to find my dremel and take care of it, the amount to take off wouldn't hurt anything (in my non-professional opinion). I might just take the front derailleur off for summer. The guard is slightly oversized, so I guess another option would be to take 1/8" in diameter off, but I don't have the facilities to do that.

    I ended up taking off my front derailleur but I kept the 2x up front. I will rarely use the granny for summer time rides. I'll put the derailleur back on for the winter. I did a manual shift down to granny last night using my shoe and it worked fine (of course coming back up to the middle ring has to be done by hand).

    I probably took a half pound off the bike by removing the derailleur, the gripshift and replacing the aluminum bars with carbon bars. I didn't notice the weight difference at all, but its there. I'll have to weigh it and see where I'm at, I suspect I'm flirting with 29lbs.

    Upgraded to XT brakes - awesome

    Converted to 1x10 with an e-thirteen direct mount narrow wide chainring and a 42t cog - feels exactly like my xx1 bike.

    Carbon low rise handlebar

    Running tubeless.

    Bike is awesome and tons of fun.

    I upgraded my Niner to XT brakes because the brakes on the Fatboy were so much better than the Elixirs on my Niner. Now the XTs on my Niner make the Fatboy brakes feel weak. Those XTs are amazing.

    Upgraded to Easton vice riser bar, Wellgo pedals, WTB seat, shimano chain (broke the stock chain) and a small frame bag. Very happy. Thinking about going to the shop and getting the lighter tubes, Probably worth it? I love this bike. I have a giant trance 29er and a new Fuji Altamira carbon road bike and all I ever ride is the fat boy! So much fun!
