You were asking about S2C wheelsets in your other thread. I'm having a hard time finding complete wheelsets with that rear hub, but of what velomine.com offers, I'd go with the Weinmann DP18s over the Alexrims ones. The front hub is better on the Weinmanns(sealed cartridge bearings), and they're better rims than the Alexrims. Additionally, the tires that come on the Alexrims are too big(38C) for your frame/fork so they'd be useless for this build. Is there a particular reason you're set on using a 2-speed hub and just going standard single speed?
