I commute here in Sacramento most of the year on my road bike, but once winter/dark/rain months (all 2 1/2 weeks we get of rain) arrive, I switch to my mountain bike. Since my mileage goes down in the dark, I also ride my trainer.
I don't have oodles and gobs of cash to spend, and really want to keep my road bike in the best shape possible and not have to replace the cassette, wheelset, chain, etc. any sooner than I have to (I ride 3-4,000 miles a year) as well as the rear tire, so I'm pondering finding a used road bike for the trainer this year. Problem is, I'm short - 5'5" - and its hard to find a working road bike that's the proper size.
I'm thinking instead that it might be MUCH simpler to find a used mountain bike and put slicks on it and slap on some SPDs for the drainer. What do you all think of that?
