This is an updated version of the Oversized Pulley Wheel System for Shimano 9100/9150 and 8000 SS/8050 SS. This new design has an integrated stop tower for easier mounting.
The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world, providing energy savings starting at 2.4 watts compared to standard Shimano systems.
The OSPW System for Shimano 9100/9150 and 8000 SS/8050 SS is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes.
It features a 13-tooth upper pulley wheel and a 19-tooth lower to provide absolute optimization of the rear derailleur, and these oversized aluminum pulley wheels come fitted with either standard or coated CeramicSpeed Bearings: your choice.
The Shimano 9100/8000 OSPW system is compatible up to a 32 tooth cassette for both Dura Ace & Ultegra derailleurs
The typical overall power savings of the OSPW System for Shimano 9100/9150/8000 is 30%-60% over a stock setup.
The oversized pulley wheels have lifespan that is 3-5 times longer than the commonly used standard pulleys on the market.
Please note: The OSPW System for 9100/9150 and 8000 SS/8050 SS is NOT compatible with Ultegra 8000-GS or 8050-GS (medium cage) derailleurs, nor with the clutch-equipped Ultegra RD RX800 & RX805. Choose CeramicSpeed's OSPW X for Shimano RX800/805 for a compatible RX800 & RX805 version. For a compatible upgrade for Ultegra 8000-GS or 8050-GS choose their Pulley Wheels for Shimano, 11s NW.
