Compared to the original Rock Shox dust covers, the Racingbros, being built with a composite material containing graphite MOS2 and Teflon PTFE, offer greater smoothness and less friction. At the same time they are more durable.
The special design of the sealing lip guarantees greater protection against the entry of dirt, mud, water etc. compared to the original Rock Shox dust covers. Laboratory tests lasting 20,000 cycles and our field tests for over two years give us the certainty that the quality of Racingbros seals is to be considered superior to oem seals
