The security and control that the Fatboy provides is unparalleled. Those fat, 27.5x3.8 tires dramatically boost your traction, grip, and floatation over the trail. We built the Fatboy with a durable list of components, like a SRAM 12-speed one-by drivetrain, that perform season after season.
A VERY FAT FLAVOR OF ADVENTURE
It boils down to a single word: adventure. The Fatboy's massive tires (27.5x3.8") float over rocks, roots, sand, snow, ice.... Let's put it this way, if it's part of mother earth, those big tires will roll right over it with a mix of comfort and traction that's unrivaled. Get out there.
• Premium, M5 alloy frame is light on the scales, yet holds up to any adventure.
• Lightweight carbon-fiber fork provides tons of compliance and absorbs chatter.
• The SRAM SX Eagle 1X drivetrain is simple, yet gives you plenty of gearing to tackle any climb.
