Rimpact Chain Damper

Introducing the Chain Damper by Rimpact.
 
The Chain Damper effectively captures chain energy, creating a smooth, silent ride. It reduces drivetrain feedback by controlling the energy in the chain as it flails. Chain Damper offers a truly chainless experience. Click Here to learn everything there is to know about the Chain Damper.

Service Intervals:
 
We've made every effort to design this product to last and be low maintenance. However, all high-performance parts need some kind of preventative maintenance to perform optimally. We recommend cleaning and regreasing the damper as soon as any noise or negative feeling occurs in the device. We also offer service kits and replacement chain rings that can be replaced by following this guide.
Should a squeak appear in the actuation, a small drip of chain lube around the seals of the damper should fix this.
