ctoddrun: That's great that you found the rim tape cause. I had that problem myself one very long day when I was trying to do a solo century but had to call my wife at 72 miles after my third flat of the day. I was ready to tear my hair out.

Today was just gorgeous.

I'm tempted to send an office-wide email offering to help out any cyclo-commute-curious co-workers. Maybe a better option would be to let them come to me.
