Wowzers you guys have a lot of bikes! I've got just the two:

Franken-MTB which was originally for commuting and now is on trail duty with a brand new 9 speed drivetrain, and the Gravity Liberty 3 that I've been commuting/going on recreational road rides on since last summer. I've been itching to buy me an old cromo 10 speed for some reason, but have yet to have one catch my eye that's also the right size.
