I'm dry fitting a ultegra 10 spd cassette over a new Aksium wheel ( I'm building slowly a cx byotch bike, call it winter project) and have a couple of small issues:
1. Body hub is about 1.5 mm taller than cassette thickness.
2. Lockring won't thread, tried several to no luck (they do nicely on my other wheelsets).
When I bought the wheelset I assumed it was a shimano compatible but now I'm wondering if I got a campy? Do they even have the same body spline?
Is there an extra cassette spacer needed for (this model) 10 spd? If so, at base or top? TIA!
