Another thread is making me think that there's something in this fixie thing (invented maybe 1870 as the safety bicycle, but I'm only 150 years late in figgering that out!) that I might want to try. I have a few frames unused and needing attention:

PX-10, UO-8, Trek 610 with low-trail fork, Trek 720 needing paint and alignment. We got long and flexy (UO-8 and Trek 720), compact, light and supple (PX-10), and some would say, stiff and not too comfortable (Super Course and Trek 610). To set these up fo geared drivetrains I would think of these and their configuration details like dropouts, cable guides and such, as well as ride and handling points.

I've thought of a few more points (just opinion), but I'll take all the help I can get!

Mods, if we need to move this over to the Single Sped and Fixed Gear section, I'm ok with it.
