Last year I was looking at aluminum bikes and made the mistake of riding a carbon bike. So I blew my budget and purchased a Trek Madone 4.6c.
I've been reading about how lighter wheels improve climbing and acceleration, so I tried the wheels on my son's Madone 6.7. The difference was immediately noticeable. So yesterday I went to the local bike shop, where my son worked for 5 summers, and spoke his old boss/owner about wheels. After awhile he asked if I would be interested in a set of carbon wheels. I told him they were out of my budget and he gave me a killer deal. They were the last set he had and since his customers were mostly triathletes they weren't big sellers and he wasn't going to get any more.
