  • OSPW for Shimano 9000/6800

    Developed and designed entirely by CeramicSpeed, the Oversized Pulley Wheel (OSPW) System for Shimano 9000/6800 provides the ultimate optimization of your bicycle's drivetrain.

    This OSPW System features a set of 17-tooth aluminium Pulley Wheels, available in red and black, housed in a specially designed polyamide (PA) and carbon cage.

    The upper and lower 17-tooth oversized aluminium pulley wheels come fitted with either standard or coated CeramicSpeed Bearings.

    The Oversized Pulley Wheel (OSPW) System is the product of choice by many of the world's leading cycling teams and triathletes.

    This specific system is compatible with Ultegra 6700/6770/6800/6870 mechanical and Di2 rear derailleurs and Dura Ace 7900/7970/9000/9070 mechanical and Di2 rear derailleurs.

    The system is compatible up to a 28 tooth cassette on most bikes depending on derailleur hanger.


    The overall power savings of the OSPW System for Shimano 9000/6700 reach 30%-60%, or more in some cases, over a stock setup.

    The oversized pulley wheels have 3-5 times longer lifetime than the commonly used standard pulleys on the market.

    The OSPW for Shimano 9000/6700 is not compatible with Shimano Dura-Ace 9100/9150 and Ultegra 8000 series rear derailleurs. For those rear derailleurs you will need a OSPW System for Shimano 9100 series.



    The Coated Advantage

    Lifetime Warranty Program
    CeramicSpeed’s coated products offer the ultimate gains in performance and longevity. Our unique coating features several attributes that improve the longevity of CeramicSpeed Bearings. The increased hardness of the races, combined with the smoothness of theCeramicSpeed Balls results in virtually no wear on the bearing.

    The coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results.

    Within our comprehensive R&D program, the special coating has been developed in cooperation with a European coating specialist. Applied to the bearing’s steel races, through an advanced process that ensures an even, smooth and homogeneous surface, the coating formula improves even further the high quality of CeramicSpeed Bearings.

    Thanks to the coating’s high resistance to corrosion – even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible. We recommend choosing CeramicSpeed Coated Bearings for unmatched longevity and incredibly low friction.
