Rimpact Chain Damper SRAM 8 Bolt

Rimpacts design integrates the chainring with the Chain Damper for a rigid, noise-free ride.

This crank-to-damper connection exceeds BCD limitations, providing unmatched durability and flex-free performance.

Long Service Intervals - Easy Service Process The Chain Damper has been designed to survive UK winters. You won't need to service it as often as some high end products thanks to its triple sealed casing that features a "labyrinth" design to minimize any water and dirt ingress. When it does come to servicing your Chain Damper, all you will need is a 3mm Allen key and some grease.

A chain weighs around 260 grams on average and the top part of your chain, (the length between the chain ring and cassette) can move at 8 meters per second, completely uncontrolled. Clutch derailleurs offer some amount of control to the lower part of your chain but the top remains free to flail wildly. At Rimpact, they think the significant effect of this uncontrolled chain energy plays a bigger part in unwanted ride characteristics than other sources of negative drivetrain feedback.

Rimpact have designed a device that can capture this energy momentarily, smoothing out the peak energy spike that usually translates to this significant drivetrain feedback. By controlling the chain's energy spikes, the Chain Damper creates a silent and calmed ride characteristic that lets the rider focus in on subtle suspension movements and the sound of tyres gripping the dirt. Ultimately a more confidence inspiring ride.
