My SL's have been fantastic, they've held up trough ~20k miles of training and racing. At 15k, I had the rear hub rebuilt, and the rear wheel trued. Haven't broke a spoke yet, I think I've crashed at least twice on these wheels (never really kept track of which wheels I crashed on
) I now race on my Reynolds sew-ups, but still use the SL's daily. I've kind of been hoping that they'll wear out, so I have an excuse for some new blingage
