    Just go tubeless! It worked so easily, definitely worth it.

    my fatboy mods so far are-

    ghetto tubeless (tried it with tape a few times but no luck)
    xt brakes
    thomson stem
    wider bars
    xtr spd's
    BEER components PF30EBB (using longer 100mm bolts)- ditched all the gears in favor of some nice shiny surly cogs

    next mod is making a custom hirth coupling extender so I can run 180mm specialized sworks cranks on the 100mm wide bb

    I too went Ghetto tubeless. Q-Tube makes a 24" tube with a 32 mm presta valve stem. So you don't need to drill out your new rim. I purchased the 24 x 2.4-2.75 size which was perfect for the specialized 90 mm rim. It had about 1/2 inch on each side of excess to trim off.

    For those that have never done a ghetto tubeless conversion check out this video. And spend the time sloshing the sealant to seal the side walls - very important:

    Sorry - I did not mean too turn this into a tubeless conversion thread, however my goal was to let people know that 24" tubes with presta valves exist - accessory item. I sure would hate to see someone take a new rim and drill it out

    As for some help - I would very much like to swap out my bar with a 20 mm riser bar. I would like to have the bar all yellow matching the paint scheme on the Comp frame. Anyone have any make model that comes close. I have looked at the Chromag "yellow ano" and it's pretty close.

    Wow you must have $$ to burn or you never ride anywhere other than the beach. I've never smacked my crankarms and pedals on rocks and such as often as I do on this bike before. I've been riding a long time and for a bike that's only a few months old those parts look like they've been around for years.

    @gravitylover, I haven't had any issues with hitting cranks and I definitely ride rocky/techy trails. I guess after riding singlespeed with 180mm cranks I'm used to timing my pedal strokes. I agree the s works cranks are pricey but they are so nice :-)

    Awesome! I want to do this too. Where did you get the longer bolts from and what was the exact size of the bolts?

    Thanks!

    Mods so far. Added a Topeak seatpost mount rack. I don't really need anything more sturdy, as I'll never be doing anything more than day trips anyway.
    I had to add a coupls spacers to spread the side...um...thingies wide enough to clear the tire.

    Other upgrades include lighter tubes, Echo riser bars, FSA stem (what' s with the nub stems that come stock?) and yellow duct tape in the wheels.

    My rear shifter has been acting up and will be replaced with an XO next week.

    I have had a couple of dirt rides on the Fatboy with the front derailleur removed and the BBG bashguard. Over the course of 3 or 4 rides the chain has dropped from the big to the granny twice. I've "downshifted" using my foot a few times with no issue. I guess I'll leave it like this for the short term and look to get this bashguard diameter reduced a bit so I can put the derailleur back on for winter. The downshifts are not that big of a deal, I can get into a small gear out back until I get to a spot where I can push the chain back over, not ideal, but no big issue either.

    Its an awesome ride in the dirt, having a blast with it.

    Hi, new guy here with a large framed specialized fatboy, I've been looking for racks that mount an integral bag, had one on my specialized hardrock rack, but cant find anything for the fatboy's. Any input is appreciated.
    Cheers,

    I just got a FSA GRAVITY LIGHT but its yellow doesn't match too well. Its more neon yellow vs mustard like the trim. I think I'll just deal with it.

    Did you get one that matches well?

    Just finished a bunch of work on my Fatboy. Made it 1x10 with a raceface 30t upfront and a Wolftooth 42t in the rear. I added a Command Post and modded the left side grip shift to operate it. Also installed a 60mm stem (large frame came with 75) and some 720mm Carbon enduro bars. Next up are SLX brakes and lighter tubes!

    Im hoping to get it under 30lbs when done.

    Its been covered a few times - a Bluto will fit without any downtube/fork knob interference. Specialized recommends (pretty strongly) the 80mm version.

    I'm so confused. What does the 80mm refer to? Is it the width, and does that mean you have to run a thinner tire up front? Sorry about the dumb question.

    One month in on my FB Downunder and no complaints whatsoever - but am thinking of planning some flightpaths. Anyone got any clues as to whether anyone on Earth is producing a dual crown fork that'll fit a Fatboy? 120mm travel? (I'd take 100...) I really want to start getting air time on my new FB and would like the softer landings front suspension would provide.
    Thanks in advance!

    Why dual crown? Why not a bluto? Put a 100 on mine and it's awesome. Planning on extending it to 120...

    I guess at my weight I'd feel more secure with dual crown. I'm 98kg (216lb)...the Bluto does look great though...and all you guys are raving about it! Hmmm...

    Specialized Fatboy Accessories

    So far


    Gravity light bars to avoid brake lever bump on frame


    Race face 30t narrow wide and removed front derailleur and shifter


    ThudBuster because I like it


    And Vee8 for summer tires with Q tubes lighter 2.8 x 26".

    Next I'm dreaming of the bluto, but maybe next year since that means new front hub too.

    After that maybe extra set of 29+ wheels for summer.

    How do you like the Vee8 rubber? I am looking for a faster summer tire. I am currently using Vee Rubber's Mission. I don't like it at all. Too much "ghost steering". I like your bars. Picture seems to show a good color match to the frame.

    Hi thumpermeister

    Vee8 is definately faster rolling than ground control and less noise. Sometimes I ride on the road with kids and didn't want to wear GC out. It has a ton of ghost steering when aired down to 6-8 which is what I ride in the woods in summer. I get used to it though. Sorta like power steering, it flops in the direction you lean. Sometimes on cross slopes it pulls too. The wider handlebars help me keep things under control and it doesn't bother me now. You can get used to it. I did a 2.5 hour woods ride yesterday on flow single track. Was fine.

    What don't you like about missions?

    Hi hans2vt:

    The missions are an excellent tire except for the ghost steering. I too run between 5-7 psi in the summer. I set them up ghetto tubeless in one attempt and they have held air ever since. Tread is reasonably fast with excellent all around traction for summer use. I pretty much like everything about this tire except for the ghosting. There have been a few situations on very tight single track where the rubber decided to take me off the trail and into the brush - such tight single track that I had no time too adjust/respond.

    I am curious to know if 45North's Husker Du have any of these ghost steering (over steering) issues. I had several rides on the Ground Controls and did not run into any issues down as low as 4 psi (I am saving the Ground Controls for winter riding). From what I have read it seems that it is VeeRubber tires in general that are only running into these problems.

    But for now I will keep riding them until I find a suitable replacement - hopefully the Husker Du.

    Thanks for you response hans2vt.

    looks great.....which crankset are you running? I have never upgraded a crankset before but I am thinking of switching my Epic S works over to a XX1 and was wondering if the XX crankset on my epic would work on the Fatboy.

    Not likely, the BB width on a fat bike is 100mm, most regular mountain bikes are 73mm.

    FWIW. It has been my experience that most tires wander/ over-steer/ bite/ self-steer/ ghost-steer below 6psi on dirt. I've had Husker Du's down in that area and the front end was downright scary sometimes. Ultimately, it's part of why I got a Bluto- I couldn't run the tires low enough to take the edge off on fast, chunky trails without seriously compromising the stability and handling. Weight, speed and terrain are also big factors when we're talking psi on fat bikes. I'm about 170 all kitted up with camel bak, etc.

    I believe that's the stock crankset. My question is, did you need any spacers or special bolts to put that raceface ring on or does it bolt directly on with stock bolts? I Need to know what to buy because I plan on doing the same thing. Thanks, and thank to others who have posted Info on fatboys it's been very helpful learning what I need to do to modify my FB properly.

    I don't know where else to put this so ... DO NOT use the regular Saris Freedom rack to transport your Fatboy. Sure the fat wheel trays fit the tires very well but the thing that holds the downtube is shaped all wrong for this bike and WILL leave deep dents in the tube. It only contacts two small points and as the bike shakes it WILL damage the frame. I tried several different ways of protecting the bike to no avail.

    Thanks....The Yakima Front loader will hold the Fat boy....but I run a ratchet strap from each side of the hub down to the cross bar, and a bungee across the rear tire to the holder....has worked good so far for me.

    The 30t race face narrow wide ring has built in spacers and actually is threaded for your chainring bolt to thread into it.

    Any ideas if this bashguard will work with the Expert? It didn't look like it would hit the front derailleur. Would I need longer bolts?

    e*thirteen Turbocharger Bash Guard 40T Black

    I read a old review on singletracks that said to get the higher teeth size (40T). Does this make sense? The expert has 36T.

    I put a 34T BBG bashguard on my Expert. It fits on the crank with longer chainring bolts, but it interferes with the front derailleur. Its only a couple of mm too big. My brother is a machinist so I could get it turned down (and I might still do that), but I just took the front derailleur off for now. I can easily shift it to granny using my toe while riding. When I want to go back to the big ring I have to stop and move it over with my hand. There's enough range on the granny that it hasn't been a problem. With all the rocks around here I felt I needed to protect the chain and chainring during the summer months - the bashguard is already missing a significant amount of paint in one spot, so it was a good investment.

    Hmm, I really think I need the front derailleur. How thick is the BBG bashguard? Maybe I can find one that is thinner that wont hit. Thx

    The problem isn't the thickness, is the diameter. I think the BBG could be turned down so you could use the derailleur, its only a few millimeters too big. You may be able to grind a little bit of the derailleur off too.

    I added a niterider 3600 light to my Fatboy for some night time beach riding... a Specialized shock pump (knowing I don't need the full shock pump but it looks cool with the gage on the down tube, I also added a Knog 4 volt usb charger rear light, and a buckshot bluetooth speaker.

    I used q tubes this year and I got 1 pinch flat. I have the regular ones, not the light ones though. Even so they are way less than stock tubes.

    Original tubes 660g
    Q-tubes*280g
