Hello, As new locking skewers that were on my bicycle for 3 rides. Cold forged and CNC machined from high quality stainless steel. Replaces 130/135mm rear and 100mm front quick release skewers. Socket style "key" that you slide an allen key through and turn the socket. Protect those expensive wheels. Check out
