The cranks are brand new and have never been mounted on a bicycle. They are prepped with grease and lock-tight. The cranks are part of a bulk order (OEM) from Shimano so there is no retail box.

Shimano XT cranks are great for almost any discipline of mountain biking. Cross-Country, trail and enduro. They are strong, stiff and light weight. And here, you are getting them at a great price.
