Interesting you should ask. So I started to wonder if perhaps my stem might simply be a hair too long. My bike came with an 80mm, which I knew right away was too short and it made my bike's steering sorta scary. I talked to our LBS about going up 10mm, but our shop buddy didn't seem to think it was worth switching out just 1cm and talked me into the 100mm stem.

So I purchased a 90mm stem on a hunch and had my hubby put it on my bike.

Hmmm...I think my hunch was right all along. While the rest of my body can tolerate being relatively stretched-out and aggressive, that 100mm stem was just a hair too long. The 90 feels perfect. Now my only discomfort is that of having tights over shorts, which just feels like too much bulk under me.
