Upgrade your Shimano rear derailleur with CeramicSpeed pulley wheels!
They ensure reduced friction and extended lifetime. Pulley wheels are the fastest spinning bearings on your bike, making an upgrade to CeramicSpeed an effective way to save you precious energy.
The Ultimate pulley wheels!
Titanium pulley wheels are extremely resistant to wear. This makes them a great choice if you ride in demanding conditions or just ride a lot. To give even greater protection and reduced friction, a super thin (2 microns) protective coating is applied to the bearing races. This further increases the resistance of the bearing to corrosion or 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.
CeramicSpeed coated titanium pulley wheels for Shimano 11s rear derailleurs are specially designed to reduce friction to an absolute minimum, virtually eliminating the drag associated with standard pulley wheels.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spun by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
