Ideal for road racing, it features a carbon cage with high-quality aluminium pulley wheels and industry-leading bearings.CeramicSpeed OSPW System Shimano 9000-6800 will add a competitive edge to your riding with smoother gear changes, watts saved and envy to all who see your bike. 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 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.

The cage is made from carbon fibre and reinforced PA while the 17-tooth pulley wheels are made from aluminium and mounted with high-quality CeramicSpeed bearings. The revolutionary OSPW System is mounted with CeramicSpeed coated bearings, which means it has undergone a special coating treatment to provide even more protection and lower friction. A very thin protective coating is applied to the bearing races, which further increases the resistance to corrosion or damage from foreign objects. The OSPW has been tested and confirmed to be the world's fastest pulley wheel system, therefore enhancing your performance with free speed, which gives you a more efficient drivetrain.

MaintenanceIt's important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity.

Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions. This revolutionary OSPW System is developed, produced and assembled by hand in Denmark. This plug-and-play product is the result of an in-depth development process and has been designed for optimal performance.
