Any question answered...

I think I've scratched my Mavic MA2 rim to death on my Thorn. Is there a rim that looks similar (plain chrome) and will slot straight into the hub/spokes already there? It's a 36-hole. And who would be good to take it to once I've found a rim?

Could just get another MA2?

halo make a retro rim which is supposed to imitate stuff like the ma2. but it has a different ERD. Maybe you could reuse the same spokes but with an extra cross. If you had 2x maybe 3x would work?
