Interesting comment , with one exception all the cantilever brakes I have come across have had a smallNo toe in required. Great feel at the bar. Stoppies at 20mph.
amount of play at the brake pivot . However the Suntour/Pedersen Self Energiser brake ( shown above ) in both it's front
and rear versions does not depend on the brake pivot to guide rotation . Instead the internal helix guide of the brake is
rigidly bolted to the brake pivot completely eliminating this as a source of trouble . And because the matching internal helix
of the brake arm is such a good fit there is no appreciable slop or play felt at the brake block
The prime reason for brake pad ' toe in ' is to compensate for the movement of the brake block under load .
If the brake block is presented rigidly to the rim there is no need for ' toe in ' as demonstrated here
