The 2016 Specialized Fatboy Expert Carbon is a top-end fat bike. Built on a light, responsive carbon frameset, geometry identical to the top-of-the-line S-Works Fatboy, designed for aggressive, nimble handling in the thick of it. Specialized's Stout hubs are laced to carbon HED rims, providing a tough, true wheelset. The 4.0" Ground Control treads are light and supple, zipping along with sure-footed confidence. Kit is substantially SRAM, including the quick, clean-shifting X01 drivetrain and sure-stopping Guide R brakes.
A very good fat bike.



Country of origin


Frame type

FACT 10m, full carbon frame, 12x197mm thru-axle rear, internal cable routing, ISCG XC tabs, suspension corrected for 100mm of travel


- An immaculate FACT carbon fiber construction ensures that the frame is lightweight and plenty stiff in all the right places. Internal cable routing is also incorporated; ensuring that slush, sand, snow, or dirt will have no bearing on performance out on the trail
- A FACT carbon fiber fork provides tons of compliance and absorbs chatter, while simultaneously keeping the overall weight of the bike down
- Alloy rims have been laced to DT Swiss 370 hubs to form a wheelset that's dependable, rugged, and efficient. So whether you're trail riding or plowing through the snow, these wheels will be the perfect mix of performance and strength
