11 speed compatible. No re-dishing of the wheel is required.
Note: 15mm axles can be identified by the axle end cap configuration. Hubs equipped with 15mm axles will allow the user to simply pull off the freehub body for easy maintenance or to swap between Shimano 10 speed and Shimano 11 speed freehubs.
Important: Older model 12mm axles that require a 5mm allen key and a 17mm cone wrench to unscrew the axle end cap for service are not compatible with the 11 Speed Shimano freehub.
