CeramicSpeed OSPW Aero Coated Limited Edition for Shimano R9100/R8000SS + UFO Chain

CeramicSpeed OSPW Aero Coated derailleur pulley in the Limited Edition for Shimano R9100 and R8000 rear derailleurs - bundle with UFO 11-speed chain

The OSPW Aero Coated derailleur pulley system for the 11-speed rear derailleurs of Shimano Dura-Ace R9100 and R9150 and Ultegra R8000-SS and R8050-SS is available for a short time in a limited edition with a shiny purple finish. In addition, you get a UFO Shimano 11-speed chain that underwent an elaborate process of polishing, cleaning and coating. Thanks to the low friction achieved in this way, you save 2 to 5 watts on 650 km in races. The Aero derailleur pulley system features a wind tunnel-tested complete cover made of polyamide-reinforced carbon. This provides a considerable aerodynamic advantage over the standard models because there is less wind turbulence. The derailleur pulleys are oversized - 13 teeth at the top, 19 at the bottom - and run on extremely low-friction ceramic bearings. Their barrel rings were additionally metal-coated to be even more durable. CeramicSpeed developed the OSWP Aero Systems in collaboration with the aerodynamics specialists at Drag2Zero.

You can find the hazardous material labelling, hazard, safety and application instructions for the oil or chain wax supplied at CeramicSpeed Oil for Derailleur Pulleys or at CeramicSpeed UFO Drip Chain Wax.

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 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 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 bearings, aluminium derailleur pulleys and a polyamide-carbon cage, making it 3 to 5 times more durable than standard systems on the market.

Coated
Coated products from CeramicSpeed offer the ultimate gains in terms of performance and durability. This is due to a unique coating that increases the hardness of the races so that, in combination with the smoothness of CeramicSpeed ball bearings, virtually no wear on the bearings can be detected. The coating is a metal layer that is 75% harder than hardened steel. It is applied very thinly (0.003 mm) and evenly over the entire surface of the race and is used both internally and externally for optimum results.
