Discover all the products for your bike at Escapa. The Ceramicspeed OSPW RS Alpha Dura Ace 9250 / Ultegra 8150 Pulley Cage and Rollers are the logical result of minimizing friction.
The new OSPW RS design is not just a visual update. The cage itself has been reinforced to offer new levels of strength and durability.
The bearing cage is made of polyamide-reinforced carbon fiber to better distribute and absorb forces, ensuring your rear derailleur operates flawlessly even under the most extreme conditions.
Ceramicspeed uses only the finest materials and the latest technologies in production to consistently achieve the highest possible quality. All products are handcrafted in Denmark. No hydraulic presses are used during assembly. Manual assembly eliminates manufacturing tolerances and guarantees a 100% perfect fit every time. So you truly use only the best on your bike!
Maintenance: It’s important to lubricate the bearings properly to maintain performance and longevity. Simply apply oil to the bearing seals, allowing the oil to penetrate the bearing. Do this every time you lubricate the chain, after washing the bike, and after riding in wet or muddy conditions.
