I've recently made a change in my setup and I'm wondering if there are any drawbacks to it. Specifically, I've taken my Ritchey stem with a 5 degree rise and inverted it so it has a -5 degree rise. I did this to lower my bars slightly, because I felt I was sitting too upright. My front end was a little high, probably because the geometry of my 2000 18.5" frame was likely designed for a fork with 80mm of travel, but my fork has 100mm.

Are there any drawbacks to inverting a stem? Will this make steering more sensitive/squirrely? The stem seems to have been designed to be flipped if desired, because the logo appears both ways, but is it a good idea to ride like this? I'd appreciate feedback.
