And as Dave above, I have XT V-brakes on my commuter/touring bike and they have plenty of stopping power. I will say though that I rented a Roubaix with disk brakes in hilly San Francisco and was glad to have them there. It was my one and only time using disks.
In the Beginning...a few years ago I scored a wonderful wheel set with disc brakes. And then - recently - I found an interesting frame set, Trek DS 8.3 for very little money. This frame can accommodate rim brakes as well as disc brakes. So I decided to try out my bike mechanic skills.
