@Chris.
Got a Mavic EX 721 rim that I'm going to get built up, but I'm not sure what diameter nipples I need.
I know I need 12mm length, but they seem to come in 1.8 and 2 mm widths. Does anyone know which one to get? I'll be using DT Swiss Alpine III spokes if that makes any difference.
Also, are the "Prolock" version worth the extra cash? What's the difference between those and the standard nipples?
Thanks.
