Upgrade your Shimano rear derailleur with CeramicSpeed Pulley Wheels for reduced friction and extended lifetime. The pulley wheels are the fastest spinning bearings on your bike, making an upgrade to CeramicSpeed an effective way to save energy. CeramicSpeed Pulley Wheels can be used for all cycling disciplines, and will last longer than any standard pulley wheels. The CeramicSpeed Pulley Wheels for Shimano rear derailleurs are specially designed to reduce friction to an absolute minimum, virtually eliminating the drag associated with standard pulley wheels.
Compatible for all Shimano 11-speed rear derailleurs, including Shimano 9100-series rear derailleurs.
Aluminium Pulley Wheels
These pulley wheels are made from a light Aluminium alloy that guarantees top performance, whatever your riding discipline. All components of our pulley wheels are of the highest quality, ensuring the best results.
Titanium Pulley Wheels
To benefit from the ultimate pulley wheels when it comes to wear and tear, we have introduced the titanium pulley wheels, which are extremely resistant to wear. This makes them a great choice if you ride in demanding conditions – for example off-road, in wet or otherwise corrosive environments. The titanium pulley wheels are also available with coated bearings to reduce friction and prolong lifetime even further.
The coated bearings are treated with a super thin (2 microns) protective layer that is applied to the bearing races. This increases the resistance of the bearing to corrosion even further, acting as a shield against the damage from foreign objects. Combining coated bearing races with a titanium pulley wheel creates a pulley wheel with extreme properties in terms of wear resistance and performance.
In a test effectuated by Friction Facts, CeramicSpeed scored 0.033w, while Shimano Acera registered 1.370. With these results, the benefits are evident. See the test results here.
To make sure that the pulley wheels perform at their best, it is important that your new pulley wheels are mounted correctly. Our videos will guide you through the process. *It is important that you properly lubricate your bearings in order to ensure optimum performance and maximum longevity. Add oil to the outside of the bearing seal, so the oil can penetrate the bearing. Maintenance for your CeramicSpeed Pulley Wheels is recommended every time you lubricate your chain, wash your bike, or after riding in wet or muddy conditions.
