Take your trail-taming abilities to the next level with the SixFifty 5500. It features a custom-formed aluminum frame with 150mm of plush rear suspension and a 150mm SR Aion fork with 35mm stanchions for responsive, predictable handling. Tubeless-ready WTB STB i35 rims paired with Kenda Regolith Pro tires combine trail-gripping traction with fast-rolling action, while the powerful Shimano hydraulic disc brakes offer precise speed control so you can rail it on the descents. An 11-speed drivetrain with Shimano SLX shifting employs a wide gear range in a compact package with tenacious chain retention so you don't have to worry about dropping a chain in the rough stuff, and a KS eTEN dropper post puts you in the best stance for speed with a quick flip of the handlebar-mounted lever.
