Q-LOC is the logical evolutionary step, guaranteeing 100% compatibility with all kinds of hub axle designs. A simple push and a little twist of the nut enables a quick removal of the axle. Exchanging the axle is as fast as extracting the axle thanks to the patented expander design which smoothly passes the thru-axle and latches safely with a reassuring click sound. Safety and speed are crucial when it comes to pressurised wheel changes during a race.Features: Upper Tubes Material: 34mm STKM Steel Lower Legs Material: Magnesium Crown Material: ACA4 Use: Cross Country (XC), Electric Mountain Bike (E-MTB) Steerer Diameter: 1 1/8-1.5″ tapered (CTS) Axle Size: 15x110mm (Boost) Left Side: Air spring system Right Side: RL-R Cartridge Damping Brake Type: Disc Brake Lockout: Remote Lockout Remote Included: No, available separatelyBuy Suntour Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
