Performance of 'safety levers'

As far as safety leavers, you can argue your case either way, but they did not get the name suicide levers for no reason. Well adjusted levers on well adjusted brakes on true rims can be setup to work ...

Are there downsides to cross-top brake levers? Compatible with all mechanical-hydraulic disc brakes?

I am a maker of custom bikes for kids and small adults. I am a heavy user of the interrupter-style levers, even for main brake levers. The main reason that I use them is that they are easy to adapt to ...

Interruptor Brakes on a Road Bike

When I wrenched for a cross team we just taped over the housing. We also would position the levers further out (unless you're running narrow bars.) Keep in mind there's no need to pull the tape so ...
