A friend is very light, 110 lbs. I love the ride of Ti, I'm 214 lbs, so I recommended her to test ride a Ti bike before she purchases a new bike. She went to two different bike shops that sell Ti (Serotta and Titus at one, Litespeed at the other), they also sell Al and Carbon. Both bike shop owners told her she would be better off on carbon at her weight. You don't get the advantages of the Ti ride unless you are a heavier person. For a light person, carbon will give a better ride. What's the story behind this?
