CERAMICSPEED OSPW rear derailleur cage system Aero Coated 

Is it still possible to perfect the already fastest rear derailleur cage system? Ceramicspeed asked itself this question and worked on a solution together with the aerodynamics experts from Drag2Zero. And it says: It works. An almost closed cage encloses the jockey wheels and the guide plates and ensures that the air can flow past unhindered. In addition, braking turbulence is avoided. Numerous tests in the wind tunnel showed that the air resistance could be reduced by up to 60% compared to conventional rear derailleurs.

The proven Oversized Pulley Wheel System from Ceramicspeed continues to work under the "shell" and ensures a significant reduction in friction. The large derailleur pulleys with 13 teeth at the top and 19 teeth at the bottom significantly minimize the movement of the chain links when passing through the cage , which is noticeable in the lower resistance. In addition, the enlarged wheels offer a longer service life than other commercially available systems.


Please note that while there are visual similarities between the Dura Ace 9100 and 9200 OSPW systems, they are not compatible with each other.

maintenance
It is important to properly lubricate the bearings to maintain performance and longevity. Simply apply oil to the bearing seals, allowing the oil to penetrate the bearing. Ideally, this should be done when lubricating the chain, after washing the bike, or after riding in adverse conditions.

a notice
When travelling, please remember to dismantle the entire rear derailleur with an Allen key, as very few bicycle transport bags offer enough space for the OSPW system.

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 pulley wheels 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.

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.

CERAMICSPEED OSPW rear derailleur cage system | SRAM Road AXS

CeramicSpeed's Oversized Pulley Wheel System (OSPW) is the logical consequence of minimizing friction. Due to the large derailleur pulleys with 15 teeth at the top and 19 teeth at the bottom, the wrap radii of the chain are significantly reduced, which is noticeable in the lower friction. In addition, the larger rear derailleur rollers offer a longer service life than other commercially available systems.

Technically, the OSPW system is equipped with high-performance bearings and special ceramic balls made of third-grade silicon nitrite (best grade achieved for ceramic bearings). The ball bearing cage is made of reinforced polyamide, with a hardened steel race and polished groove. The CeramicSpeed bearing balls are 15% harder, 100% smoother and 99% more resilient than standard ceramic balls. CeramicSpeed bearings are considered the best ceramic bearings in the world.
The bearing cage is made of carbon fibers reinforced with polyamide so that the forces can be better distributed and absorbed and your rear derailleur works perfectly even in the most adverse conditions.
