    i understand that canti levers pull less cable and v brake levers pull more.

    what does this have to do with the safety aspect of using V brake lever with canti brakes?

    thanks in advance.

    What it means is that you need to pull much harder to get the same braking force. If you ride off
    road or in the rain, this is probably not a good thing.

    "V-brake" levers pull the cable twice as far, half as hard.

    If you use them with traditional cantis or calipers, your grip needs to be twice as strong for the
    same amount of stopping power.

    Hey. Some Vbrake levers have a Max/Min cable setting. Setting the lever to pull the least amount of
    cable and adjusting the cable hanger quite low will help develop some power but Sheldon is right,
    even this method will probably require up to 1-1/2 times the force at the lever to stop (at best)
    versus a traditional canti - lever. Take care. Keith.

    depending on what you are trying to do, you might want to check out the "Travel Agents" that
    tandemers are commanly using these days with STI shifters and V-brakes. They are a little
    double-roller thingy that sits at the end of the cable and makes the travel of a road STI lever work
    ok with v-brakes... stops a tandem quite well actually!

    if you are going the other direction, maybe you could reverse the travel agent?!

    The problem one's likely to have is that the levers will bottom out or almost bottom out even with
    the pads set very close to the rim.

    No, that's the opposite, that's what happens when you use conventional levers with direct-pull
    ("V-type") cantis.
