Collection: CeramicSpeed

CeramicSpeed is synonymous with extremely low friction, high durability and uncompromising performance. For years, the Danish brand has been a pioneer in ceramic bearings and other high-end bicycle components that make a noticeable difference – for both professional riders and ambitious amateurs. At Transition Zone you will find a carefully selected range of CeramicSpeed products, including bottom brackets, pulley wheels, OSPW systems and wheel bearings. Whether you are chasing marginal gains for your next triathlon or want to upgrade your road bike with the most efficient components on the market, CeramicSpeed is an investment in speed, efficiency and mechanical superiority.

CeramicSpeed was originally created with a background in roller bearings for the industry, but their breakthrough in the cycling world came when their solutions were tested and recognized by WorldTour teams. Since then, they have been a fixture at the pro-tour level, where even milliseconds count. For you as an exerciser, this means you have access to exactly the same technology that the world's best riders use - and that's exactly what makes CeramicSpeed unique.

One of CeramicSpeed's most iconic products is the OSPW (Oversized Pulley Wheel) system, which replaces the small standard pulley wheels in the rear derailleur with larger wheels and an optimized cage. It sounds simple, but the effect is significant: less friction, better chain line and thus increased watt savings. In fact, tests show that you can save up to 2.4 watts - a number that makes a difference when you're sitting in an aero position for several hours or fighting your way through a tough time trial.

OSPW is available for both SRAM, Shimano and Campagnolo drivetrains, and comes in both standard and SLT (Solid Lubrication Technology) versions, which require minimal maintenance. SLT technology means that the lubricant is encapsulated in the bearing itself, giving it an extremely long life without the need for frequent cleaning or re-lubrication. For many riders, it’s not just about going faster, but also about having a setup that lasts and works flawlessly mile after mile.

A CeramicSpeed bottom bracket is not like most. Where traditional bottom brackets have steel bearings and standard seals, CeramicSpeed uses hand-crafted ceramic balls that are harder, smoother and more precise than any conventional solution. The result is up to 75% less friction and up to 10 times longer life. That means more energy for propulsion and fewer watts lost in the transmission – something every cyclist can feel.

Whether you ride with BSA, BB86, BB30 or PressFit, there is a compatible CeramicSpeed solution, and you can be sure that every single component is manufactured with extreme precision in Denmark. They are used not only in the crank – but also in the wheel hubs and even in the headset and rear wheel bearings. The wheel bearings in particular are popular upgrades, which improve rolling resistance and responsiveness, especially during acceleration and in technical corners.

The big question is often: Is CeramicSpeed worth the money? For many exercisers, it seems like a huge investment in equipment that doesn't immediately seem to make much of a difference. But the difference is noticeable. Not just in speed, but in the feeling of a more responsive setup, fewer service needs and the mental boost that comes from knowing that your bike is equipped with some of the best the market has to offer. It's not just performance – it's confidence.

At Transition Zone, we are happy to guide you to the right solution, whether you are looking for a bottom bracket, an OSPW system or simply want to upgrade your wheel bearings. Our selection is curated with a focus on quality, and we are always ready with technical advice. And it doesn't stop there: We also offer installation of CeramicSpeed products in our professional bike workshop, so you can be sure that everything is mounted correctly and optimized for your setup.
