CeramicSpeed OSPW coated derailleur pulley system 9000 / 6800 - drivetrain optimisation


The CeramicSpeed OSPW coated derailleur pulley system for Shimano Dura Ace RD-9000 and Ultegra RD-6800 allows you to optimise your drivetrain. It consists of two oversized 17-tooth aluminium pulleys (available in black or red) with super-smooth CeramicSpeed ceramic bearings and a special carbon-polyamide cage that reduces weight. In addition to the 11-speed mechanical rear derailleurs mentioned above, the model is also compatible with Dura Ace RD-7900 and Ultegra RD-6700 10-speed rear derailleurs as well as Dura Ace RD-7970, Ultegra RD-6770 (10-speed) and Dura Ace RD-9070, Ultegra RD-6870 (11-speed) electronic rear derailleurs. Like all oversized Pulley Wheel (OSPW) systems, the Shimano version also stands for less friction compared to standard pulleys and allows a significant power savings. In the coated version there are also other advantages: A metal coating of the bearing 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.
