I'm mostly riding a Trek touring bike, aluminum frame, 24 gears. The touring bikes are a little more durable than sport bikes, wider tires and such, more suitable for the kind of road that Maine DOT sees fit to provide. And I need that "Granny gear" third chainring on the hills. Gray hair and ancient legs, you understand.

Also have a much older Raleigh mountain bike, also aluminum frame, that I use in the spring when the roads are at their annual finest, and on the carriage trails down at the national park.

If you aren't careful, you'll get my lecture about leaving bikes outside in the rain....
