Q-LOC Thru Axle Quick Release: Q-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.
