CeramicSpeed OSPW coated derailleur pulley system for Shimano 9100 / 8000-SS - the ultimate upgrade


With the CeramicSpeed OSPW derailleur pulley system for Shimano Dura Ace RD-R9100 and Ultegra RD-R8000-SS, you can upgrade your drivetrain with performance and durability. It consists of an upper pulley wheel with 13 teeth and a lower pulley wheel with 19 teeth (black or red) based on super smooth ceramic bearings. A weight-saving carbon retainer is also used. Compared to the predecessor model, the assembly has been simplified with a stop bolt. In addition to the 11-speed mechanical rear derailleurs mentioned above, this system is also compatible with the Dura Ace RD-R9150 and Ultegra RD-R8050-SS electronic rear derailleurs. Like all Oversized Pulley Wheel (OSPW) systems from CeramicSpeed, the Shimano version also stands for less friction compared to standard pulleys and enables significant power savings. In the coated version there are also other advantages: A metal coating of the races increases the already strong performance, the durability increases and there is almost no wear of the bearings.

Technology:


OSPW
The Oversized Pulley Wheel System (OSPW System) is a ground-breaking innovation from CeramicSpeed developed in collaboration with world-class triathletes. This unique system stands for 40 - 60 % less friction compared to standard pulleys and enables power savings of at least 1.6 and up to 2.4 watts. This was confirmed by the Friction Facts test laboratory. The OSPW system features unique CeramicSpeed bearings, aluminium pulleys and a polyamide-carbon retainer, making it 3 to 5 times more durable than standard systems on the market. True progress in the field of cycling performance.

Coated
Coated products from CeramicSpeed offer ultimate gains in performance and durability. This is ensured by a unique coating that increases the hardness of the races so that, in combination with the suppleness of CeramicSpeed ball bearings, practically no bearing wear can be detected. The coating is a metal layer which 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 inside and outside to achieve an optimum result.

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.
