Due to many, many requests to bring back this product we are now making them again. The levers will work with any kind of brake, and feature fully cnc'd construction and hinged clamps. They come with the lever pivot pin in the hole closest to the handlebar. This location is for road calipers, center pull cantilever brakes, and road cable pull disk brakes. Moving the pivot pin to the outer hole location makes the levers compatible with v-brakes and mountain cable disk brakes. The CrossLever can also be used on it's own. Just let the head of brake cable sit in the recess for the housing that runs between the two levers. For a tiny little lever that clamps on the "grip" area of a drop bar check out PAUL'S E-Lever
