Overview
About this bike
The KHS SixFifty 6600+ is a capable machine designed around modern technical trails. It features a full carbon frame with internal cable routing, 160mm of plush rear suspension, and a burly Fox Float 36 fork to tackle everything from big-mountain enduro to rowdy backcountry exploration. Integrated armor in the downtube protects against kicked-up rocks, and a metal plate on the driveside chainstay guards against chainslap. Tubeless-ready WTB Scraper i35 rims paired with Kenda Regolith Pro tires deliver striking traction across a variety of terrain, and Shimano hydraulic disc brakes put loads of power in your fingertips for precise control on technical descents. A 11-speed drivetrain with Shimano XT rear derailleur 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 Suspension Rage-i dropper post puts you in the best stance for speed or efficiency with a quick flip of the handlebar-mounted lever.
