Mavic CXP-33 and Velocity DeepV have a very sharp profile PLUS the Velocity DeepV has a joint sleeve that increases nipple depth. Result is that if you are not careful - the bottom of your spoke wrench will scratch the anodized finish when using 10mm and 12mm nipples.

Basically, the nipple sits to deep in the rim with the wrench flats ending up to close to the rim surface.

14mm nipples are ideal for the Velocity DeepV...it's what I use when the customer okays it.
