Product Description

Offering unparalleled security and control the Specialized Fatboy Comp is a Fat bike that takes the mountain bike to the next level.

At the core of the Fatboy is an M4 alloy frame with trail friendly geometry. It is long and low with short chainstays for confident handling both uphill and on the descents. The frame tubes are butted to shave extra weight and a tapered head tube gives you a stiffer front end. The FACT carbon composite fork is stiff whilst absorbing vibrations from rough trail surfaces for a more comfortable ride.

The SRAM XO/X9 1x10 speed drivetrain, is paired with a Race Face Turbine Cinch chainset and delivers slick shifting over a wide range of gears with excellent chain security.

The Specialized Stout wheels feature 4.6” Ground Control tyres that offer endless amounts of grip as well as absorbing the bumps on the trail so it feels like you are floating over the rough.

Ride the fat tyre revolution on the Specialized Fatboy Comp.
