The oversized pulley wheel (OSPW) system for Shimano 9000/6700 is fully developed and designed by CeramicSpeed, offering the ultimate optimization of your bike's drivetrain. This OSPW system consists of a set of 17-tooth aluminum shift rollers, available in red and black, housed in a specially designed polyamide (PA) and carbon cage. The upper and lower 17-tooth oversized aluminum pulley wheels are equipped with either standard or coated CeramicSpeed bearings.

The OSPW system is the product of choice for 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, as well as Dura Ace 7900/7970/9000/9070 mechanical and Di2 rear derailleurs. The system is compatible with most bikes up to a 28-tooth cassette, depending on the derailleur bracket.

The OSPW system combines the highest quality materials with a unique design to provide reduced friction and longer life, improving your competitive advantage. Thanks to the OSPW system for Shimano rear derailleurs, the power savings start at 40%, and the CeramicSpeed bearings inside guarantee a three to five times longer life compared to standard rollers on the market. Wattage savings with a CeramicSpeed OSPW system for Shimano Dura Ace and Ultegra start at 2.4 watts.
