I just bought a 48 Orbea Onix Dama, and I don't find her squirrely at all. She's quite fast, nimble and stable at the same time. I haven't found anything about her that I'm not in love with. The only thing that's taking time to get used to is going from 3 chain rings to 2. And the only time I have problems there is figuring out which hills I can do in the large ring and which ones I need to switch to the small ring before I start up. There's nothing worse than having to go down a chain ring mid hill. Bleh!

A bicycle does get you there and more.... And there is always the thin edge of danger to keep you alert and comfortably apprehensive. Dogs become dogs again and snap at your raincoat; potholes become personal. And getting there is all the fun. ~Bill Emerson, "On Bicycling," Saturday Evening Post, 29 July 1967
