Polo Bikes

the problem solver has a problem with the running of teh cables, plus the main cable going to the lever is just hold by a 2mm screw, the black one you can see in the pic

Em and Gabes both use it and they both change to double brake levers

double brake levers.

On the contrary, Mark and Mike both run them with no problems.

The only major downside i see, is if one cable goes, both your brakes go.
