Wrong Title. It's not an XD driver.
Yeah it says xd driver in the title and on every piece of paper and email I got regarding this purchase, but it comes with an xdr driver. I paid for expedited shipping because I desperately needed it for this weekend and now I'm stuck with a wheel I can't use. This is so unfair, and I could never trust REI ever again if I need something urgently.
