What does that mean?

You can get all Endless rubbers from us at a fair price. We source directly from Endless, so they are original rubbers and not fakes! We always have the latest compounds and developments such as the N39S! Do you have questions and need advice? Feel free to contact us at

Here is a small guide to the different compounds:

Endless MX72 (for the road, mountain passes)

Coefficient of friction: 0.37 - 0.47 µ Operating temperature: 50-700°C The Endless MX72 is a sports rubber, especially for sporty riding. This Endless consists of a ceramic-carbon-metallic compound. The low noise and dust levels are additional features of this sports brake pad. The cold braking effect is also very good. The Endless MX72 is very temperature-resistant. Despite its very high initial bite, the Endless MX72 is very gentle on the discs. Ideal for sporty riding on roads.

Endless ME20/ME22 (Trackday, Clubsport)

Coefficient of friction: 0.35 - 0.40 µ Operating temperature: 150-800°C The Endless ME20 is a racing rubber with a semi-metallic compound developed for rallies and circuit racing. This Endless has practically the same coefficient of friction over the entire temperature range, even at temperatures of over 600° degrees. The wear behavior of both the ME20 and the discs is low. The Endless ME20 also performs very well in cold seasons and wet conditions. The Endless ME20 is also ideal for use on the rear axle in conjunction with the MA45B on the front axle.

Endless N39S (circuit, hill climb, slalom, rally)

Coefficient of friction: 0.42 - 0.52 µ Operating temperature: 0-850°C The latest racing rubber from Endless N39S is a further development of the popular N35S. The N39S has a very high initial bite with fast friction build-up from cold. It is a very responsive compound with excellent modulation and is suitable for high grip and downforce applications. Ideal for hill climbs and slalom where perfect bite is required from the first corner and a constant coefficient of friction is desired over the entire distance. The N39S is very heat-resistant and has very low pad wear. We recommend brake ventilation for small brake systems.

Endless MA45B (long distance)

Coefficient of friction: 0.33 - 0.38 µ Operating temperature: 300-800°C The Endless MA45B is a racing pad, especially for long distance races. The coefficient of friction is not as high as that of other racing brake pads, making the Endless very durable and gentle on the disc. It is therefore more economical in the long term than other pads. Various top teams (Manthey-Racing, Raeder-Motorsport etc.) use the Endless MA45B in the 24-hour race at the Nürburgring.

Comparative example of wear during the 24-hour race on an Audi TTS:
With Endless MA45B = 1 pad and 1 set of discs
With Pagid RS29 = 4 sets of pads and 2 sets of discs
