A high performance machine, introducing the Specialized S-Works Fatboy Mountain Bike 2017. With a full FACT carbon fibre frameset, hydraulic disc brakes and the smooth shifting of the one-by SRAM XX1 11-speed drivetrain, this is a fat bike ready for peak performance.
Specialized S-Works Fatboy Mountain Bike 2017
Specialized S-Works Fatboy Mountain Bike 2017
The king of fat; Specialized's S-Works Fatboy Mountain Bike 2017 combines the top-end features of the American manufacturer's more svelt off-road option with the supreme grip and versatility of fat bike tyres and geometry.
Despite the massive 26x4.0" tyres, this bike still maintains a relatively lightweight construction, thanks to the strong and stiff FACT 10m carbon fibre fork and frame. Mounted to this frameset are the SRAM Guide RS Carbon hydraulic disc brakes. These strong and graduated disc brakes combine with the unbeatable traction of the Specialized Fast Trak Control fat tyres to ensure ground-breaking stopping power over the loosest of terrain.
The drivetrain is also geared towards responsive and zippy fun. SRAM's XX1 11-speed system provides smooth and reliable on-by shifting and the 10-42 rear cassette makes sure you have the gears to get up and over even the toughest of hills.
Available in a ultra-sleek carbon, black and red colour scheme, this bike looks every bit the elite performance machine out on the trails.
An immaculate, FACT carbon fibre 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 fibre fork provides tons of compliance and absorbs chatter, while simultaneously keeping the overall weight of the bike down
HED Big Deal carbon wheels are light, fast, and 85mm-wide to make sure that you get all the traction and floatation that fat bikes are known for, only without a weight penalty or having to make any sacrifices to climbing prowess
26x.4.0" Fast Trak Control tyres make short work out of any trail condition. They accelerate fast, while providing a game-changing level of traction, control, and floatation for better handling out in the wild
Race Face Next SL crankset leads the way in the drivetrain department, providing a simplified, efficient, and almost impossible to drop your chain kind of ride quality
