Lately, I've been interested in getting a Velocity Aerohead O/C (in a 622 BSD) for a wheelbuilding project. The problem I'm running into is that the numbers on the rim's lateral offset are not consistent from site to site. QBP claims that it is 3.0 mm, while Velocity claims that it is 4.0 mm.
So, I'm not sure who is right, and would rather not risk pulling the trigger on an Aerohead O/C until I have some more-definite number I can plug into Spocalc.
Has anyone had an opportunity to measure the lateral offset on an Aerohead O/C? If so, what kind of number did you get?
