    Fatboy Pro Trail

    2016 Fatboy Pro Trail

    When it comes to trail riding, traction, floatation, and control are the name of the game. So it comes as no surprise to us that we're seeing more and more trail riders getting rowdy on fat bikes these days, which is why we created our Fatboy Pro Trail specifically for trail riding. It features a durable and efficient carbon one-by drivetrain and powerful Shimano brakes that'll stop on a dime. And to soak bumps, hits, and chatter, we equipped this Fatboy with an air sprung suspension fork from RockShox. Go faster, go fatter.
