Very nice. I made a few minor changes to the commute bike and it is silent like a ninja now. I'm into the time of the year at work where the hours are killing me and the commute may be the only exercise I get for awhile. Saturday I had to work from 10 to 2 (no, not 4 hours, 16 thank you) but I was able to get in 12 miles during my dinner break. My coworkers saved me a couple of slices of pizza while I did an out-and-back time trial to Sac State.
