When I got to work this morning I forgot my undershirt, but it wasn't too bad. I think I figured out why my ride was so tough today, when I put my wheel back on last night I think my brakes were too tight. The rim kept rubbing on the brake pads.

The ride home this afternoon was pretty tough. There is an awful hill on my way home. Even in the lowest gears I was struggling up the hill and had to dismount halfway up. Hopefully the rubbing brakes had to do with a bit of the problem.
