Rocky Mountain ALTITUDE C50 Bike Born to Descend. If your favorite part of the ride is the steep, rough descents, the Altitude C50 is a machine purpose built for high speed aggressive riding, technical predictability, and absolute dominance on the world's toughest stages. Out back, a Fox Float X Performance shock gets a tune matched to each frame size. Up front, the 38's GRIP damper keeps the fork steady through rock gardens and hard landings. A Shimano SLX shifter and XT rear derailleur run a 10-51T cassette for a wide climbing range. Shimano XT Trail 4-piston brakes with a 203mm front rotor bring strong stopping power on long descents regardless of the condition. WTB rims come ready for tubeless with tape and valves included, and the Race Face Trace rear hub has 10-degree engagement for quick pickup on technical climbs. A Maxxis Assegai up front and a Minion DHR II outback give you traction on loose, steep terrain. A Race Face Aeffect R dropper with up to 175mm of travel gets the saddle low before you drop in.
