Overview
About this bike
You get one bike to rule them all with the trail-taming SixFifty 6600. It features a full carbon frame with internal cable routing, 150mm of plush Fox Float rear suspension, and a responsive and stiff 160mm Fox Float 36 fork to tackle everything from big-mountain enduro to rowdy backcountry exploration. Tubeless-ready WTB Scraper i35 rims paired with Maxxis Rekon 27.5 x 2.8-inch 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 1 x 11 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 Kind Shock E30i dropper post puts you in the best stance for speed with a quick flip of the handlebar-mounted lever.
