ok, so I'm building up a single speed road bike, and I've got a fixed gear. the fixed has the base line IRO wheels, which are awesome and are holding up damned well for having a 270 lb person skid stopping on them.

I need a rear wheel for the single speed. Two options:

1. but a wheel for the single speed, would probably be an IRO, although I would like a flip flop free/free rear hub, I can do with out it.

2. buy a new wheel/set for the fixed, and put the IRO's on the single speed. Would be a great time to upgrade my wheels.

so what would you do? if you went for an upgrade, what would you upgrade to?

also while I have your attention, know of anyplace I can get red brake cable housing?
