We know that we're not blowing any minds when we say carbon is pretty cool. Compared to an alloy frame construction, it keeps weight down, does an exceptional job of absorbing bumps and vibrations, and it allows us to take more liberties to fine tune the ride quality. For these reasons, we made the Fatboy Expert Carbon.

It features an immaculate FACT 10m carbon layup that performs the aforementioned, while also allowing us to integrate fully internal cable routing. And in keeping with the theme of blending performance with efficiency, we built the bike up with a top-notch, X01 one-by drivetrain and SRAM's fan-favorite Guide R brakes. The Fatboy Expert brings new efficiency and fun to the fat bike category.

  • An immaculate FACT carbon fiber construction ensures that the frame is lightweight and plenty stiff in all the right places. Internal cable routing is also incorporated, ensuring that slush, sand, snow, or dirt will have no bearing on performance out on the trail.
  • A FACT carbon fiber fork provides tons of compliance and absorbs chatter, while simultaneously keeping the overall weight of the bike down.
  • HED Big Deal carbon wheels are light, fast, and 85mm-wide to make sure that you get all of the traction and floatation that fat bikes are known for, only without a weight penalty or having to make any sacrifices to climbing prowess.
