Patience is a virtue. Take your time, it'll happen.

I'm a 56cm size rider, and I've never had a problem finding an SLX bike, just finishing my third, and I sold an SLX 54.5 frame today.

Intriguing to me is the Excell tubing on the Giordana frames that are still available new. Framebuilders seemed to really like the tubing, and they are handsome frames, for sure.
