    Building a carbon fat bike!

    My next project i want to build a carbon fat bike. I am looking into importing one of the asian carbon frame and fork sets as it seems like they are the same frames all the big makers are using anyways. They are around $700 delivered with frame and fork. They have 26" carbon fat bike rim sets for $200/set. So the investment is low enough to take the risk i think. As for components i'd like to use a Shimano XT set but not sure yet if everything will fit. Has anyone here ever done a ground up fat bike build? Any advice on components? I'd do a gates carbon drive but the frame has no cutout to fit the belt so i am going to go with chain set.

    Um yes, but no one I know has gotten one of those chinese frames yet, they are not available quite yet.

    I got a carbon chinese frame, but it was more like $1700. Most all of the carbon fatbikes originate in China, no matter who is selling them.

    You will not be able to use Shimano components, because shimano does not make fat-bike cranks. Raceface turbine cranks are decent though and not a bad weight to strength to money ratio. The ultimate is the raceface hollowgram right now. Sram makes fatbike cranks too. You won't end up with shimano hubs, again, they don't make any. Hubs are coming out from many other companies now, so you have a pretty decent selection. A shimano cassette and chain work pretty well though, so you can do that. I'd suggest a clutch derailleur whatever group you decide on, your tire options expand quite a bit if you run one chainring up front, and in that case the clutch derailleur + narrow-wide ring allows for no chainguide (and it works too, I've done two downhill races on snow at ski-resorts this winter, no chain issues all winter or summer). You can do shimano pedals, except that when it's cold pedals, cleats, and crankarms become big heat-sinks and such all the warmth out of your feet, so flat-pedals win in extreme cold. No problems with snow packing newer shimano pedals though, it just pushes out thankfully.

    Carbon rims are more than $200/set. Even chinese 29er rims are about $350/set. Fatbike ones are more.

    Talking direct to the manufacturer to get the frame and fork. They said 2-3 months for a 21". Thanks for the advice! May as well do sram components.

    Quoted 610+ 80 shipping for the frame and fork and 200 for set of carbon rims. Not bad!!

    Still waiting on the frame. Should be July 7th. I'll post parts as they show up. I decided to also build a rigid 29er carbon as well - that frame and fork just showed up today and its really nice! Frame weight is 3.06# for 21" frame. 3k weave.

    $200 was what the OP was hoping to score the rims only for, not complete wheels.
    Nuke the entire site from orbit. It's the only way to be sure.

    Yeah they sell the rims only for about $200 or full wheel set around $540 which seemed like a better deal for me!

    Carbon 29er is almost done! Had to convert BB30 to BSA to run the XT cranks but got that done now all thats left is i need a high clamp XT front derailleur and need to bleed out the brakes and that one is done. Looks amazing too!

    How's your frame, did it arrive already? And what about the crankset, is it from Samox?
    I am also interested in buying a similar set from them.

    Frame has been ready for a bit but they are still waiting on the crankset from samox. They said end of July so i am having them paint my frame while we wait for the cranks.

    Heh, looks good!
    Which exactly cranks are those, I'm interested in Q-factor - is it 220 something or perhaps more manageable ~200?

    Thanks! I don't recall but i think they are the only cranks Samox makes for fat bikes. crank and BB set was $140.
