Pentagon hub for more safety and optimum braking performance
The Disc version of the Lightweight MEILENSTEIN is equipped with a so-called Pentagon hub. The hub sleeve was developed and patented by Lightweight. It provides more safety because the wheel hardly twists at all when braking. In the Magura endurance test the Pentagon hub proved to be "indestructible".
Magura is known for its uncompromising testing procedures for disc brakes, in order to test the brake components for maximum load capacity. One of these methods is special full-load braking, in which a wheel is brought to a standstill under full load at a speed of approx. 50 km/h within seconds with maximum braking force. After several weeks of testing, the Lightweight development manager received a call from Magura. He was informed that the MEILENSTEIN wheel had survived 8000 of these full-load braking operations without damage. The previous maximum values of comparable disc-braked wheels were 6000-7000 braking operations before they were damaged.
A few months later, Magura engineers spoke to the development department again and reported that that MEILENSTEIN C DISC wheel had been left on the test bench and was still intact after no less than 20,000 full-load braking cycles. As it could not be broken, the tests were stopped, the wheel was measured and checked for technical values. It turned out that these were exactly the same as when they were delivered.
The reasons for this are mainly due to the unique concept of the MEILENSTEIN DISC series. The braking forces occurring on one side were analysed and as a result the patented Pentagon hub was developed and used. Together with the firmly laminated full carbon spokes, each of which can absorb around 1.8 tons of traction force, the Pentagon hub forms the technological basis for a safe and durable wheel that is second to none. The MEILENSTEIN DISC series was revised and extended by Tubeless - this is how the MEILENSTEIN EVO series was created.
