Mountain bike good for the road?
I know it sounds like a ridiculous question, but can anyone give advice on a model that might be good on the road as well as decent on a trail?
I have a mountain bike and my wife would like to go with me on occassion, but she also would probably prefer to ride in the neighborhood more often simply for exercise. Since a road bike cannot be used in the mountains, but a mountain bike can be used on the road, and I cannot afford 2 bikes, then a mountain bike seems like the right choice. I'm just wondering if there are some mountain bikes that are better suited for mountain and road. I'm looking in the $550 range but would probably scan craigslist before I ever spent that much for a new bike. Thanks for anyones help.
