I have two new sets of 105, plus a lightly used set of 105 w/ Ultegra R/D. Used set has a 34.9mm clamp on F/D. I haven't priced nor pictured the used set yet, but it would obviously be less than the new set.

I wanna go fast!

I've got a full Ultegra 10 speed set for you - F&R 6600 STI shifters, rear 6600 derailleur, front 6500 derailleur (28.6mm clamp) or front 6600 derailleur (31.8mm clamp). The front derailleurs are functionally the same and visually almost identical. All used, a few scratches here and there. PM me if you're interested.
