Fatboy Expert Carbon

2018 Fatboy Expert Carbon

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.
