I've a pair of M900 hubs that I want to build up. Now BITD I never really paid any attention to the different rim specifications, pretty much wheels were wheels. So what would be a good rim to build up a pair of XTR hubs with? Probably erring to the lighter rather than the sturdier side. What wheels did you build up BITD, period correct is not majorly important but if there are any recommendations for a mid/late 90's build all the better.
