Specialized's Fatboy Expert Carbon is a bantamweight in the plus-sized world. By incorporating carbon, they've elevated the fat bike platform to a higher level of performance, strength, and efficiency. This trail-eating champ is built around a svelte FACT 10m Carbon frame and vibration-quieting carbon fork. Tubeless 4-inch wide Ground Control tires are wrapped around lightweight HED Big Deal carbon wheels that provide trail-shredding stability while flying up climbs. While you're eyeing new and offbeat places to roll your Fatboy, you can count on the efficient 11-speed one-by SRAM X01 drivetrain powered by carbon Race Face Next SL cranks to get you there quickly. When it's time to slow it all down and take in the scenery, SRAM Guide R brakes are on the case. Sand? Snow? Mud? The Fatboy is one light fatty that backs it up with ability.
