XDR driver fits great but doesn’t come with the required end cap deeming it useless. Would not buy this as you won’t be able to use it unless you get an end cap elsewhere.

This XRD driver is great. However, BE ADVISED this does not come with the required XDR end cap to be able to install this driver on a wheel and use it. Further, the XDR endcap for the LN Driver is not easily sourced. So, that is my reason for the 2 star rating. To Performance Bicycle… please stop selling this as a selectable additional purchase, when buying new wheels, unless you are going to also going to provide the required XDR endcap.

Thank You.
