Specialized's Fatboy SL is a supermodel in the plus-sized world. You'll get caught drooling over the smooth welds and sweeping curves of the M4 alumium frame, and the beautifully smooth and simple FACT carbon fork. Where it really counts is the SL's giant pair of shoes—massive 4.6-inch Ground Control tires and super light HED carbon wheels that devour any terrain. The SL is dressed up with SRAM's top end XX1 1x11 drivetrain, an incredible Race Face Next SL carbon crankset and Magura's petite yet powerful MT8 hydraulic brakes. A Specialized carbon handlebar and seatpost complete the build. The Fatboy SL is the perfect combination of light and fat that's just begging to get out on the trails and shred.
