I forgot to check avg. speed both directions, maybe this doesn't matter. But time wise, there was no difference between a regular commute and today; less then an hour in each direction.

Today, I proved to myself at least, that I could do this. The ride wasn't to difficult, although the late night ride home, between 11:30pm and 12:30am, I usually back off to unwind from work.

As for the gearing; I like the upper limit and could reach 20 mph. But really didn't like the gearing for riding into a headwind. If I go this route, I may opt for a 46 x 17 combo.

All the fixed gear talk has perked my interest, I'd like try a fixie sometime, too.

Thanks again for all the insight.
