There is often a worry that when using the front brakes on a bicycle that it could propel you over the handlebars. That would stop you in more ways than one. This is where the Slidepad system comes in.
It actually allows both the front and rear brakes to be applied on a single lever, but in such a way that the front brake won’t lock up and turn the bicycle into a catapult! This works with traditional-style cable and housing running from the handlebars to the rear brake – but the system only works with rim brakes not the more modern discs.
As the user squeezes the brakes it operates both the rear and front – with the latter being activated being just a split second earlier, thus ensuring a smooth braking.
