Uber clyde here (310#). I ride a Redline 925. I've had a few problems with breaking spokes in the rear wheel on the stock wheelset, but it does have a lot of miles on it. I had my LBS check it out, and they said the problem was the spoke tension was too low. The wheels are formula hubs laced to something that looks like 36h alex rims.
I have velocity fusions (36h front, 40h rear) on my roadbike. Those have been bulletproof. I also ride a cheapo set of 28h/32h vueltas on another SS bike I have. Those have worked out surprisingly good.
I just ordered a new wheelset - formula track hubs with weinmann DP18's. 36/36. Pretty cheap on ebay, and seem to have gotten good reviews on these forums.
Now that my fixie is my daily ride - it feels funny to ride my ultegra road bike.
