I went from a 120 to an 80 and twitched all over the place when I got above 30 mph, and the handling was so shaky that I couldn't even hold my line while reaching for a water bottle. It was better with the longer steam, but the reach was too much and my hands were constantly going numb (along with other appendages). I now have a custom bike that actually fits and distributes my weight properly, and the difference is night and day. I might suggest that if you need such a short stem, you're on the wrong bike.
