Cage CeramicSpeed OSPW for Shi 9250/8150
The CeramicSpeed Oversized rear derailleur pulley and basket system (OSWP) is proven to be the fastest pulley system in the world, saving up to 2.4 watts compared to standard Shimano systems.
With the Dura Ace 9200 and Ultegra 8100 system, you save 30%-60% more power than with the original system.
For CeramicSpeed, the OSWP system is a flagship product, chosen by many of the world's top cycling teams and professional triathletes.
Upper 13T pulley and lower 19T pulley is to provide the best optimization for the rear derailleur. Upper and lower Oversized aluminum pulley comes with either Standard or Coated CeramicSpeed bearings.
OSWP has a 3-5 times longer lifespan than regular pucks.
Please note : Although the 9100 and 9200 OSPW systems look similar, they are two different products and cannot be interchanged. Not compatible with the R7150 rear derailleur.
