Regardless of what Sheldon said, rest his soul, cantilevers are a royal pain and really don’t stop better. All the physics in the world could never bring them back after V-brakes. The CX canti’s made a comeback with V-brake pads, but discs will return them back to the parts bin.
I say this with a bike that has very good cantilever brakes (XTR) and I still hate setting them up. I will need to get good V-brake replacements soon as they are quickly disappearing from sight.
