Shimano quick release skewers are reknowned for their quality, ease of use, strength and utter reliability. The cam action design of the locking arm is progressive and firmly secures your QR hub/wheel. As you'd expect, XTR skewers carry the flag for the brand. Stainless steel axles, machined aluminum lever arm, steel ends with knurled surfaces, titanium springs and the M9000 grey finish all declare dominance.
