I could run a cable loose with a calliper on it that could be gripped between the teeth, for no hands braking. Brake pads round the wrong way for enamel-friendly cushioning?
Squeezing a caliper will just loosen the other one won't it? As it frees up cable. not tightens it.
I think you'd need to ride around with it squeezed and let it go when you want to apply the brakes.
Yeah, i think i'll struggle to mount them to the bars...
