More efficient power transfer
In this derailleur cage, CeramicSpeed applies several technologies that reduce drivetrain resistance to give you more efficient power transfer, allowing you to ride faster while pedaling less powerfully. Thus, you can save up to 14 watts and beat the competition!

OverSized Pulley Wheels
CeramicSpeed has fitted this derailleur cage with oversized jockey wheels that make the chain line more efficient, reducing drivetrain friction. As a result, you cycle faster at the same wattage.

Ceramic bearings
The bearings in the pulley wheels of this cage are ceramic. They are more efficient and durable than regular bearings and reduce friction in the drivetrain.

How does the OverSized Pulley Wheel system work?
The OverSized Pulley Wheel system by CeramicSpeed is designed to improve the performance of your bike's drivetrain. The use of larger jockey wheels makes the chain line more efficient, resulting in less friction and higher speed. This innovative system helps to better transfer your power output to the wheels, allowing you to achieve more speed with less effort.

What are ceramic bearings and what are their advantages?
Ceramic bearings are special bearings made of ceramic material. They are more efficient and durable than traditional bearings, resulting in reduced friction in the drivetrain and a longer life. Thanks to the use of ceramic bearings in the pulleys of the OSPW RS 5 Spoke cage, you will experience improved performance and reliability.
