    Newbie Brake Lever Question

    I have an older road bike, that the prior owner had installed a flat handlebar on. I would like to update the brake levers. It has older style, caliper brakes: dia-compe Alpha 5000. Will a dia-compe DP7N lever work with these brakes?

    Well, I should be more specific. You may need a new brake cable with a different end. But that's easy.

    A quick glance at the Google search results for " dia-compe DP7N " indicates the lever is meant for newer direct-pull cantilever (Shimano V-brake) or mechanical disc brakes. It will have a different cable pull ratio than your brake caliper requires.

    I was thinking the same thing, the bikes I saw with these levers have linear pull brakes. But then again, some levers will apparently work with either type , such as the ones available from Nashbar. How can this be when canti's and linear pulls require a different cable pull ratio?

    Those levers may have two places the cable can anchor to, like the Shimano flat bar road bike shift/brake levers I had.

    Makes sense. I've never seen any of those in person, so I don't know. One thing's for sure, the linear pull levers I have definitely don't work well with canti's/calipers, and the canti levers I have don't work well with linear pulls.

    I would say to the OP that there's a good chance those Dia Compe levers won't work well with caliper brakes because they probably pull the wrong amount of cable-
