Its robust construction also makes it suitable for use with E-MTB, as it can handle the increased speed, torque and power that’s produced by electric bike motor systems. Benefitting from lightweight magnesium lower legs and an ACA4 crown, it ensures an excellent strength-to-weight ratio for smooth and reliable handling on every ride.Air Spring and LO-R Cartridge DamperPerfectly suited for cross country (XC) racing as well as handling the extra torque and speed produced by electric mountain bike (E-MTB) motor systems, this suspension fork features a lightweight air spring to keep you in full control of your ride. Its air spring provides excellent smoothness and consistency when tackling rough terrain conditions, while its LO-R cartridge damper soaks up any knocks and bumps along the way. Coming complete with disc brake compatibility, the Suntour XCR 34 LOR DS Air Boost Fork provides powerful front-end suspension performance with the ability to mount your favourite hydraulic disc brakes.Q-LOC Thru Axle Quick ReleaseQ-LOC is a patented quick release system for thru-axles fully deserving of the name “quick”. 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: LO-R (Speed-lock with rebound adjust) cartridge Brake Type: Disc BrakeBuy Suntour Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
