A movement or development toward a destination or a more advanced state. Specialized's S-Works FSR 6Fattie rips corners, rolls over anything and defines progression. Rolling on beefy Specialized 650B x 3.0-inch tires that are mounted to 30mm-wide carbon rims, this plus-sized beauty delivers supreme control. But it's not just about fat tires; the FACT 9m carbon frame, dialed geometry, and 135mm of travel make this Stumpy an absolute riot to ride. Complete with Speclaized's innovative SWAT door, this Stumpy has a compartment in the downtube to hold tools, a tube and a pump, so it's always ready to get out there. Components wise, the S-Works is loaded with carbon and checks all the boxes. A plush 150mm-travel Fox Factory 34 Fork? Check! Remarkable Shimano XTR brakes? Check! A SRAM XX1 1 x 11-speed drivetrain and a Specialized Command Post dropper with plenty of adjustment? Check and check! The only thing missing is a rider that's ready to climb aboard and put it through it's paces. It's a good thing you can take care of that.
