Swissstop, or rather the company Rex Articoli Tecnici SA, based in Mendrisio, is presenting the "Catalyst" at Eurobike. This is a brake disc made of high-strength stainless steel that is riveted to an aluminum carrier and will be available in 140, 160, 180 and 203 millimetre diameters.

On the way to the finished product, the Swissstop engineers had completed a lot of research work. Since the beginning of 2015, the engineering team has carried out a series of laboratory tests on brake discs and designed digital models of these rotors. The thermodynamic simulations, structural and material analyses and fluid dynamic visualizations were carried out in cooperation with the Rapperswil University of Applied Sciences for Engineering.

In particular, the heat transfer in the individual models was observed and a design for the new rotor was determined, which should be particularly heat-resistant when exposed to the airstream with asymmetrical slots. Internal tests are said to have shown extremely effective heat management, significantly shorter braking distances, very low wear and structural durability under heavy braking.

The rotors are compatible with all organic and sintered pads - and are said to deliver even better braking performance in cooperation with Swissstop's exothermic pads, which have cooling fins.
