Skinny tires are for the road; Specialized’s Fatboy is for everything else. This lightweight aluminum frame is mated to a FACT carbon fork on 4.6-inch Ground Control tires that devour everything in your path. The super-wide aluminum rims give you stability and durability to roll through the most root-filled trail like it’s butter. With SRAM X7 drivetrain components providing slick shifting on all-day adventures or snowy cruises, you’ll be sure you get the push you need when speed’s what you’re after. And, you can bring it all back down to earthly limits thanks to the Tektro Gemini hydraulic disc brakes. Trail? Sand? Snow? The Fatboy owns it all.
