Just wanted to pass on a relatively new wheel builder/company. . .ROL Wheels. I have recently purchased a set of their ROL Race SL wheels to replace my Bontranger Race Lites and I can't believe the difference they have made. At 1550 grams and aero design, I have an increase in speed of nearly one mile per hour (during winter rides) which has reduced my hour times by nearly three minutes. I really didn't think this was possible by just upgrading wheels, but the proof is in the numbers (just look at some of my times on Motion Based). The owner, Sean, is great to deal with and he does what it take to get things done for his customers. The wheels grams per $$ is outstanding and they hold up to daily training and racing. They also come with great tubes and rubber. Look them up at rolwheels.com
