I have 3 bikes - Commuter (drop bar Schwinn Slicker - 1x9) - MTB (rigid Trek Sawyer 29er - 1x9) - SS MTB (rigid singlespee KHS Solo One 26er). My weekend rides are almost always MTB rides. That being said, I wouldn't hesitate to take the commuter on a joy ride (as long as there weren't crazy hills on the ride).
