I've got a couple different choices to make to build up my new commuter. I ride into work (~7 miles) in the early AM, ride 1.5 miles round trip at lunch to get to the gym, and then rack the bike on the front of the bus for the ride home (85% downhill into work means 85% uphill on the way home )

So I'm leaning towards a road-bike type commuter, but was interested in how many of you went the road bike frame route, and how many went the mountain bike frame route when it came to building up your commuter. It'll be interesting to see how this plays out. Oh, and if you don't mind sharing, post up your distance and reason like my example above (15 miles round trip to work? school? etc.) and spec out your ride!

NOTE: This is a general poll. If your bike is a cruiser with 26" tires, then I guess you can opt for MTB. A touring bike with 27", 700cc. or 650b wheels would fall under road for example. There's a ton of bike types, I just tried to make the poll pretty general.
