Hi,

Built a kilo tt from the ground up a few weeks ago, and i'm trying to get the perfect length for the stem. Rode 45 mi with a 80mm stem, and it felt a little short. Had a curve in the lower back too. Went to the lbs and got the cheapest possible 90mm stem ($5) to try that for length. Here's a couple of pics, does that look like the right length? It definitely feels a lot better, but I wonder if I should go with a 100mm?
