I just joined this forum and already have found some excellent advise. My wife and I took up riding this summer as a way of exercising together. She commutes to work on a Giant Cypress and I got a GT -nomad (hybrid). We learned very quickly that these were too heavy for anything more than short hops. I put 28c Gator skins on mine and saw a huge improvement.
This still was not enough and I just got my Jamis Satellite, hers is still on order. I love having a "real" road bike, I would have liked to get the "Quest" model but could not afford 2 of them. I think that for me a steel frame was a good choice.
Looking forward to doing the local MS150 this summer.
