I'm working out the specifics for a weight weenie-ish fixed gear wheelset for my commuter, I'm looking at a velocity hub (a regular road hub) up front laced to a kinlin xr-270 rim and I haven't decided on rear hub, but it will be laced to a kinlin xr-300 I'm thinking a 28/32 spoke count should suffice. As far as spokes/nipples go I'm going to leave that one up to the wheel builder and my wallet.

if you really want to geek out, you can play with different configurations at the link below and get an estimate of what the set would weigh, they probably wont have the specific hub you're going to use but you can select one with a similar weight to get a rough estimate
