I somewhat object to the notion that dual pivot brakes somehow stop faster than flexy old fashioned sidepulls or centerpulls. I believe that any brake is limited by the quality of the pads and the rim interface. I have not yet owned a bike that I could not cause to lockup either the front or the rear wheel. Locking up the front or even coming close will cause an over the bars accident, and locking up the rear is just a waste of good rubber and bad technique. I have never owned a dual pivot but I have ridden them, and can not remember being shocked by the short stopping distances over classic systems. I am sure that there is something good about dual pivots but I don't think it can be shortened braking distance. Garth Libre in Surfside Fl.
