Going fat isn't just a fun way to ride—it's a ride revolution. The security and control that the wheel system found on our Fatboy provides is unparalleled. You get dramatically more traction, grip, and floatation than with traditional mountain tires, all without sacrificing much to climbing efficiency.
The end result is easy to explain—you have way more fun. And to make sure of it, we built the Fatboy with a durable list of components, like a SRAM 11-speed one-by drivetrain, that are low-maintenance and eager to perform season after season. Have more fun—go fat.
- The frame features an M5 alloy construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
- A FACT carbon fiber fork provides tons of compliance and absorbs chatter, while simultaneously keeping the overall weight of the bike down.
- The SRAM NX one-by groupset keeps things simple, and is ready to take on the trail for the long haul.
