Hi Gents & Ladies

Was curious if anyone knows what the spec is for the rear hub on said bike. It is my b'day soon and I am looking to get a Mavic Ex721 rim fitted to the stock hub. I spoke to Specialized UK and they are unable to tell me. I want to get my LBS to do the build but wanted to order the spokes from CRC as the LBS will charge approx a hell of a lot more for them than CRC (thats if CRC do the right size).

Any info is most welcome.

Thanks in advance

Wil
