Powertap conversion - which rim?

Meek One said:

Going to convert my PT Pro to track (fixed). I'd like a ~50mm rim to go on it. Anyone know who makes a good 50mm 32h rim? I checked Zipp's site and didn't see any 32hole options for the 404s, Blackwell didn't list any rims let alone a 32h. Thoughts?

Thanks.

try Rich at wheelbuilder.com

He can get Zipp rims drilled to spec for any normal spoke count. Or he can suggest an alternative. If you are going to use as a track rim, then maybe a good idea to go for the 360, which is the Zipp 404 but stronger (extra laminate layer designed for track) and no braking surface.

I'd second Alex's recommendation of Rich.

But, as a point of reference, the "360" is just the standard 404 rim. If you're sourcing your rim yourself, you'll need to ask for the "360 track."
