hows the wheels mfg working for you? gotta CAAD10 on the way and not sure whether it's worth taking the plunge with a full praxis bb. Haven't heard any bad things about the wheels mfg shims...
Had my wheels mfg for a good 2 years now, no problems with it. All I did was one year in I popped the adapters out to clean out grit with a q-tip and popped the bearing shields off to check grease levels. All fine and dandy.
Dafuq, those kogels are expensive!
I used wheels mfg for my red gxp cranks to fit to bb30 and it only cost me £30.
Here's one for shimano
