That's a very large can of worms. It feels pretty darn good. Right now I have a 100mm stem, and the next size larger frame has a 15mm longer top tube, so I'd likely have to go to a 90-95 stem. I've tried several online bike fit systems, and one professional fitting. Ideas appreciated though.

And thanks for the link to other KiloTT posts. Based upon its popularity, I think some attempt at keeping track of variations/models/dates is worthwhile.
