My Avail is a 2009. It was like brand new. The girl I bought it from thought she would like road biking but hated it, She was an avid runner, and had lost 100 lbs! My bike is a small WSD frame. I am 5"3, and it fits me nicely. I kept thinking the top tube was too long, but as I have ridden, I realize it was more my inexperience and stiff arms than wrong sizing. I did have the seat post adjusted.
I decided to wait on the purchase of another used bike. This one is really good for now. Funny you mentioned steel frame. My husband is an avid reader, and likes to know something about everything, (a man thing) but is really into reading about steel frames. We are going to Colorado Springs in a few weeks. He found a guy on the web that makes steel frame bikes, custom fit. Low and behold, he is in Colorado Springs. We may be checking out steel frames soon.
So much to learn, but would rather just enjoy the ride!!
