  1. Recently decided to change from drop bars to North Road style bars on
    one of my bikes.
    The previous levers were non-aero style for drops. Dia-Compe brand I
    believe. Brakes themselves are also Dia compe caliper.Swapped out the
    bars and put on some levers that I had which had been on a mountainbike
    that was running old canti brakes. The performance improvement going
    from the drop levers to the upright bar levers was like going from weak
    drum brakes on a car to power 4 wheel disc. In other words a very big
    improvement. I have never been really happy with the performance of
    drop bar levers/brakes with the exception of those on one bike with
    canti's. Braking from the hooks on this bike is very good.

    I use lined housing, Kool Stops, set up without excessive housing loops
    ect.

    My question is why the difference? It would seem levers designed to
    operate with drops should work as well as lever designed to work with
    upright bars.

    Thanks

    More leverage, more cable pull means more powerful braking.

    Your statement is contradictory, and there isn't any more cable pull.

    Thanks doctor....the MTB lever pulls more cable and the things have
    more leverage, probably why they are more powerful.

    OP said canti brake levers.

    The lever pulls more cable *and* it has more leverage? How is that possible?

    Or did you mean to say that the /lever/ pulls more cable but the
    /caliper/ has more leverage? That would be a true statement.

    I think he meant that the finger position on the MTB levers allows more
    leverage on the brake lever than on the aero levers, i.e. the fingers are
    farther from the pivot point during normal use (on the hoods).

    I guess that's what I meant. I have used MTB levers with road calipers
    and it indeed makes for strong braking.
