New brake disc from Tektro: The TRP Rotor S05E promises 10 per cent more braking power

With the new S05E, TRP presents the next development stage of its own rotor. The MTB brake disc is available in diameters of 203 mm and 220 mm and has a thickness of 2.3 mm. The rotor has been specially designed to increase braking performance by 10% and also offers improved heat management. Thanks to this innovation, riders can gain an important advantage even in the toughest conditions, which can make the difference between victory and defeat. But even without competition, the new TRP brake disc increases safety when braking on an MTB.

Analysing an improved pattern of smaller, laser-cut holes has provided important insights. These more frequent holes help the rotor to reach the ideal operating temperature quickly and cool down efficiently at the same time. This is particularly important on descents and difficult routes, where rapid changes also require a precise braking response.

Simply put, this brake disc heats up faster and is more temperature stable on descents because the positive and negative space (open and fixed areas) on the brake disc is more evenly distributed. - Colin Esquibel, TRP engineer

I've been using the new TRP rotors for almost a year now and immediately noticed a sharper feel on the lever when you pull the lever for the first time. As a racer, your braking points are super important and this is a big help when you're braking at the last second. - Oisin O' Callaghan, YT MOB

TRP Rotor S05E: Different mass distribution ensures better heat management

On long and challenging mountain bike descents, the S05E rotor maintains a constant temperature, ensuring consistently reliable performance. It dissipates heat effectively, preventing overheating and allowing the rider to stay in control and ride with confidence.

This rotor was specially developed for use in the World Cup, where it was put to the test - one of the toughest tests for bicycle components. The S05E rotor reduces heat build-up during heavy use and regular braking, both in racing and normal riding. This results in consistent performance and safe braking actions on trails.
