This is a used Xero Cxr6 24 spoke rear road wheel with a Shimano CS-5600 11-25 Cassette and Bontrager Skewer.  I used this exclusively for my trainer and it has low miles on the cassette which I bought new a few years ago.  The wheel was used when I bought it and has some wear as show in the pictures. Great for a trainer wheel or on any road bike.  I moved to 11spd on a new bike and can't use this setup anymore.  Please email any questions before bidding, Shipping to CONUS only (tbd based on location).
