TheCeramicspeed OSPW Shimano DA9200/ULT8100 12V STD pulley cage and pulleyssystem is the logical result of minimizing friction. The large derailleur pulleys—with 13 teeth on top and 19 teeth on the bottom—significantly minimize the movement of the chain links as they pass through the cage, resulting in lower friction. Additionally, the larger rear derailleur rollers offer a longer service life than other systems available on the market.
Technically, the OSPW system is equipped with high-performance bearings and special ceramic balls made of third-grade silicon nitride (the highest grade achieved for ceramic bearings). The ball bearing cage is made of reinforced polyamide, with a hardened steel raceway and a polished groove. Ceramicspeed ball bearings are 15% harder, 100% more flexible, and 99% more durable than standard ceramic balls. Ceramicspeed bearings are considered the best ceramic bearings in the world.
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.
IMPORTANT:When traveling, remember to remove the entire rear derailleur using an Allen wrench, as very few bike transport bags offer enough space for the OSPW system.
