Factory Description
Specialized’s Fatboy Pro starts every day with a big breakfast of gnar-nola, wheelies, and shredded trails; it’s not a picky eater. With a RockShox Bluto suspension fork and massive 4.6-inch Ground Control tires, it has the appetite to devour rocks, sand, snow, and whatever else you shove in front of it. Those fat tires are mated to wide aluminum rims that can take a beating and give you stability even on loose terrain. While you’re eyeing new and offbeat places to roll your Fatboy, you can count on the SRAM X01 drivetrain with a Race Face crank to get you there quickly. When it’s time to slow down and take in the scenery, Shimano XT brakes are on the case. There’s even a Command Post dropper so you can climb like a skinny kid, and descend like the rolling mass of traildozer you are. The Fatboy Pro is always hungry for more, so go ahead, be a glutton.
