The CeramicSpeed OSPW System Coated Shimano R9100/R8000 is an upgraded version of the Oversized Pulley Wheel System designed to enhance your cycling experience by providing smoother gear changes and energy savings of up to 2.4 watts compared to standard Shimano systems. This system features a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel for optimized rear derailleur performance. The oversized aluminum pulley wheels come with either standard or coated CeramicSpeed Bearings, which help to reduce friction and improve energy efficiency.
The OSPW System is not compatible with Ultegra 8000-GS or 8050-GS (medium cage) derailleurs, nor with the clutch equipped Ultegra RD RX800 and RX805. It is also not compatible with the 12-speed Shimano 9200 or 8100 series derailleurs.
The OSPW System is designed for use with Shimano 9100/9150 and 8000 SS/8050 SS and is compatible with up to a 32-tooth cassette for both Dura-Ace and Ultegra derailleurs. The system has been extensively tested and proven to be the fastest pulley system in the world, with energy savings ranging from 30%-60%.
The OSPW System is made from high-quality materials, and everything from the bearings to the cage is designed to provide optimal performance and maximum longevity. The system has a lifetime that lasts 3-5 times longer than standard pulleys, making it a reliable choice for professional cyclists.
It is important to properly maintain the OSPW System by lubricating the bearings using the lubrication points on the back cage plate. This should be done when lubricating the chain, after washing your bike, or after riding in wet or muddy conditions.
The OSPW System is produced and assembled by hand in Denmark and is a popular choice among professional cyclists and teams. However, it is important to note that the OSPW System may not fit in most bike travel bags and should be dismounted with an Allen key when travelling
