V-brakes w/ non-V-brake levers

Anyone know of any adapters to run V's w/o V-levers other than the
World Class V-dapter??

Thanks,
K.

Ibis has one called a love unit.

In any case, what kind of levers do you have now? You may not need
an adapter at all.

The 900M models that are the re-labeled DiaCompe SS-5 Mk.IIs ?!? If
so then no, those are not compatible with a long-arm, sidepull cantilever
as they only yank 16mm of brake cable. Your about 7mm below the shimano
reccommended minimum (which is conservative since most people I know
setup their V's with less than 2mm of pad clearance and never use even
half their V-lever travel).

To figure out how much cable pull you need, you have to consider how much
pad clearance you plan to use. The brakearms are so long that you have
to move the ends (where the cable goes) about 3mm for each 1mm of pad
movement. But since your actuating BOTH arms off the same brake cable
you need to double this cable pull to 6mm JUST to get the pads to contact
the rims. Now since brakepads tend to deform a bit when they first
apply pressure, you can expect to require at least double this amount
to get a good amount of braking action out of the pads. So now your up
to 12mm. Now, imagine you wanted 2mm of pad clearance... suddenly
you need 18mm of cable pull... 3mm of clearance needs 24mm of cable pull...
and so on. In OTHER words... if you ONLY plan to use 1mm of pad clearance
then yes you can try it with your coda levers. Oh do take note, if the
lever feels soft with the Coda levers, its because of the extra leverage
that regular levers tend to have that is reducing the amount of force
that you have to apply with your fingers to still get good braking
at the wheels.
