This is the stem i've had on the bike pretty much forever. It has over 7000 mi on it, but now i'm wondering if i'm too stretched out on it.. A few years ago, I built another road bike (a scattante), with a little bit more modern geometry, and a longer top tube. That bike has a 110mm stem, and feels pretty much perfect. Would it make sense to measure the top tube length on the scattante, add in the 110mm stem length, and try to create that same distance on this bike? The reason i'm fiddling around with the idea of changing the stem is that my back has been hurting after riding this bike, so i'm wondering if it's a bike fit issue (or maybe just an issue from moving to a much hillier area?).
