I'd ask on the mechanics section. (I'm just not knowledgeable enough.) I'm over three hundred still and there is no way I would ride a lowspoke count wheel yet. (I was under the impression that disk brakes were a poor choice for uberclydes like us. If you think about how the forward inertia on the bike is really stressing the spokes when you brake with disks... it kinda makes sense. sorry.)

I find the tall thin guy at R&A knowledgeable and very helpful. The shorter hispanic guy I avoid. I've gotten "advice" from him I think is absurd. The other staff there is mixed but they seem to know what they know. (IF you know what I mean.)

I also find it a horrible shop to browse. Brand (or Carl Hart...) is a shop I can just wander around. But if you ever wanted to just look at an incredible collection of high end frames -- that is the place to go.
