I really love my C.F. Edge. Made a few alterations to it. I put some horizontal bar ends on. That seems to work better for me than verticle. Then, out on the end of those I installed some Bar con shifters. Also, had to install some Rotor cranks on it. I run 406x28 Continentals, I think they roll great. I've got about 22-2300 trouble free miles on my machine in a year and a half. That thing is an engineering marvel. I bought it because two of my friends have trikes. I thought it would be fun but, it's way more fun than I ever thought it would be. It's like driving a sports car, only with a much better workout.
