I decided to try out a mustache bar setup on my Ciocc I'm building up right now. So I went with a smaller stem I had over the 100mm Cinelli 1A stem I had on it. I had a 60mm SR stem I acquired in a trade. So I just tossed it on and it completely changed the look and feel of the bike. So I jump on to arrange the levers and I thought my stem was loose. Everything was tightened up but I could flex the stem enough that I'd be leery of doing some aggressive riding.

Has anyone come across this with stems? I thought with the short 60mm stem it would be pretty stout but it feels the complete opposite. It's below the minimum insertion line so it's not sticking out without enough material in the steerer tube. Is it just the SR stem?
