Technology:

Ceramic Bearings by CeramicSpeed
CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other commercially available bearings. All CeramicSpeed bearings are manufactured by hand in Denmark under clean room conditions and are subject to a strict four-stage control procedure. Among other things, the size of the ceramic balls is checked down to the thousandth of a millimetre. Tests are then carried out in the laboratory or preferably by professionals in training and competition. CeramicSpeed bottom brackets guarantee you the lowest possible friction, optimised power transfer and maximum durability and also help you save watts and reach the finish line faster. It's not about seconds, it's about minutes!

OSPW
The Oversized Pulley Wheel System (OSPW System) is a breakthrough innovation by CeramicSpeed, developed in collaboration with world-class triathletes. This unique system is known for 40 - 60% less friction compared to standard derailleur pulleys and allows power savings of at least 1.6 and up to 2.4 watts. The OSPW system features the unique CeramicSpeed bearing, aluminium derailleur pulleys and a polyamide-carbon cage, making it 3 to 5 times more durable than standard systems on the market. A real advance in the field of cycling performance.

X Offroad
Dirt, rain, mud and gravel are the most important components of a true off-road adventure. But these conditions put a lot of strain on your components and force you to change the bottom bracket, hub bearings and derailleur pulleys frequently. CeramicSpeed Offroad bearings extend the life of the most stressed parts of the bike and reduce friction. Designed to withstand the harshest conditions, they allow you to go longer, harder and faster. With their stainless steel races, they are corrosion resistant and offer exceptional performance.

Note from the manufacturer:

The rear derailleur should be completely removed before transporting the bicycle in a travel bag, otherwise the OSPW System could be damaged.
