Tektro CR720 Cantilever Brakesbrc15153
For all of those reasons---jabbing/getting kicked/lousy fit on small bikes---they went extinct about fifteen years ago.
But now they've made a comeback, and there's a reason for that. High Profile cantilevers feel better. To most people and us included, they have a subjective quality of positiveness and crispiness that is lacking in other designs, and you get a small good gush every time you apply them, and brakes get applied a lot.
In other matters not related to the great feel, these are also top-notch. They are cold-forged, light and strong, have good pads, the World's Best straddle wire hanger, and easy-to-use independent spring adjustment on both sides. They set up easily as cantilevers go, and have a lustrous soft silver finish that looks good on any bike for many years.
One bikes worth.
Buy the 54mm length yoko replacement insert pads after you've done a lot of riding, I mean braking. Note: these brakes used to come with the longer 73mm pads so be sure and check what's on your bike before ordering new pads.
