So after much debate and a nights sleep - I decided to buy the cheaper model of my current bike. Not only will the geometry be identical, but it'll save me roughly $1200. It doesn't have the best of components on it - but I thought I could wear those down this winter with the intent of putting my worn Ultegra from my racing bike on the trainer and then upgrade the racer. Ahhhh... I should sleep much better tonight!

I debated using my racer through the winter as well - but with all of the rain I ride through in the PNW it would wear my nicer components out quicker than I'd like them to be worn. Hence, the option for buying a separate trainer that I can beat up with less remorse.

Oh and Caligirl - I mean trainer as in the sense of riding a bike out in the elements - not on the indoor trainer. Sorry for the confusion!
