CeramicSpeed ​​Oversized Pulley wheel System RS Alpha for Shimano 9250/8150

CeramicSpeed is synonymous with precision, speed and innovation. With roots in Denmark and deep ties to professional cycling, the brand has managed to build a global reputation as one of the most uncompromising manufacturers of bicycle components. With us you will find a carefully selected range from CeramicSpeed, including their prepared chains, chain wax, bottom brackets and the characteristic oversized pulley wheels. All products have one common goal: to reduce friction and maximize efficiency for riders who want the absolute best.

What sets CeramicSpeed apart from the competition is not just their technical precision – it’s their consistent pursuit of marginal gains. In a sport where seconds count, and where both professionals and ambitious exercisers value every watt, CeramicSpeed has become the preferred choice. The technology behind their products has been developed and tested in collaboration with some of the world’s biggest cycling teams, and it’s clearly visible in every detail.

A large portion of the energy in a bike's chain is lost in the drivetrain, and that's where CeramicSpeed's chains and lubricants come in. Their prepared chains are treated with extremely low-friction wax, which minimizes energy loss and extends the life of the chain. Unlike traditional chain oils that attract dirt and degrade quickly, CeramicSpeed's wax-based solutions offer a cleaner, more efficient drivetrain.

Their proprietary chain wax has become a popular alternative for riders looking for low maintenance and high performance. It lubricates without attracting dust, works in both wet and dry conditions, and significantly reduces friction compared to classic lubricants. Many triathletes and road racers choose to ride with waxed chains on race day to get the last few percent out of their equipment – and CeramicSpeed is among the most trusted names in the industry.

CeramicSpeed's most iconic product is undoubtedly their oversized pulley wheels, which have become a fixture on many professional bikes. By increasing the size of the pulley wheels, the angle the chain has to bend around is reduced, resulting in lower friction and thus more efficient power transfer. The combination of large pulley wheels and ceramic bearings provides a significant improvement in performance - especially over long distances, where energy conservation becomes crucial.

The ceramic bearings in both the pulley wheels and bottom brackets are in a class of their own. They are extremely hard, light and smooth, which means less resistance and longer life compared to traditional steel bearings. CeramicSpeed machines their bearings with a precision that far exceeds the industry standard, and it is felt in everything from acceleration to ride comfort. It is not only on the lab paper that the difference is clear – it is something that can be felt out on the road.

CeramicSpeed bottom brackets are known for their unmatched durability and stiffness. They ensure that all the power you put into the pedals is converted into propulsion – without being lost in bending, rubbing or spillage. Many people choose to upgrade their bottom bracket as the first step towards a more efficient bike, and for good reason. It’s not about bling or fashion – it’s about performance.
