Specifications: Application: Road Gearing: 12-speed Cassette Teeth (max.): 36-tooth Compatibility: SRAM Rival AXS Technical Information: Derailleur Pulleys: 15 tooth (upper derailleur pulley), 19 tooth (lower derailleur pulley) Outer Cage Material: polyamide, carbon Inner Cage Material: polyamide, carbon Other Materials: aluminium Bearings: Ceramic Features: oversized derailleur pulley system with ceramic bearings, offering unique durability and performance reduced friction and increased energy savings for a highly efficient drivetrain high-performance bearings with very hard, above-average smooth and resilient ceramic balls made of grade-3 silicon nitride (best achievable grade for ceramic bearings) two spring tension options compatible with 10-36 12-speed cassettes handmade in Denmark 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 cleanroom 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 millimeter. 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, optimized 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 from 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. Manufacturer's Note: Before transporting the bicycle in a travel bag, the rear derailleur should be completely disassembled, otherwise the OSPW system could be damaged.
