Crossed bike mechanic off the list last night of potential trades I could pursue if I ever wanted a change of pace.

Two nights ago noticed my BB7 disc brakes were feeling a bit mushy, so tightened in the pads. Was incredibly happy with my work, especially on the rear brake where the brakes seemed incredibly responsive on my ride to/from work yesterday.

Got home last night and backed my bike into the garage only to hear squeaking; my sensitive ear quickly pinpointed the rear disc brake. Picked up the rear end of the bike, pedaled with me hand, and the wheel stopped after ~2 rotations. Apparently I'd tightened the brakes so much that the inside pad was pressed right up against the rotor; so much that there wasn't the telltale 1 rub per revolution sound that would indicate it was just a LITTLE too close. It was so close it was rubbing the whole rotation.

Funny thing is that it didn't really affect my time. Wonder if the brakes basically just canceled out the purported ~20W of reduced rolling resistance for my new Conti GP 4 seasons compared to the old Schwalbe Marathons I switched out of last week?
