Roller cam brakes to canti's?
The mid 80's Peugeot Canyon Express I just picked up has roller cam actuated brakes. The bosses seem similar, so I'm wondering if I could replace them w/ newer cantilever brakes. The cable routings seem ok for canti's...
Thanks,
Frank

Roller cam Pivots are above the rim.. so you may get a U brake to work , but not cantilevers , because then frame pivot has to be below the rim, ie closer to the axle.
of course you can hire a frame builder's shop, to remove the pivots , and braze them back on where the have to be for cantilevers or V brakes ..

Because rims and shoes vary, it's often necessary to use washers to move the shoes close to the rim to get them set right.
This need to set the travel, by way of adjusting shoe/rim clearance with washers is what made these lose their cachet. Another example of a good idea that didn't wok because people don't know how to set it up correctly.

nowadays cantis seem to have same fate, displaced by V-brakes and disks
one of only 2 mechanics in a 5 mech shop who can setup cantis properly

Charlie Cunningham of WTB, who sold rights to have the roller cam brake copied , Had even more complicated brake designs..
