Every now and again, we're all faced with going on a diet. The same is true for our Fatboy. With the Fatboy Comp Carbon, we've taken performance and strength up a notch, while also moving up a wheelsize, to a 27.5 wheel and tire combo.
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.
• Light-yet-tough carbon frame holds up to any adventure you can throw at it.
• Lightweight carbon-fiber fork provides tons of compliance and absorbs chatter.
• The SRAM GX Eagle 1X drivetrain gives you plenty of gearing to tackle any climb.
