The Shimano XTR M970 skewer is one of the best skewers ever introduced to the market. It has a super smooth action and beveled edges for easy operation. The eccentric cam inside the skewer head allows the rider to tighten the skewer without having to apply a lot of force. This is the reason Shimano skewers work so well, you can tighten the skewer with almost no effort.
The M970 skewer lever, lever head and nut are anodized black alloy for durability and reliability in the field. A broken skewer is a show stopper and the last component you want to fail when you're on the trail.
