Isolates Feedback
Removes unwanted drivetrain feedback when descending, resulting in a quiet and confidence inspiring ride with a chainless feel.
Improved suspension sensitivity and feel
With less drivetrain feedback, you'll become more aware of your bikes suspension movements, with an increase in grip and confidence.
Less rider fatigue
By isolating the rider from drivetrain feedback, you'll feel less tired at the bottom of a descent, allowing you to ride to your limit for longer.
How does it work?
Chains have significant mass. This uncontrolled mass is free to flail, causing unwanted feedback and noise. We believe this plays a bigger part in unwanted ride characteristics than other sources of negative drivetrain feedback.
The springs in the Chain Damper capture the chain's energy, smoothing out the ride.
The Chain Damper isolates the rider from drivetrain feedback which is caused by the chain flailing as we descend. Bringing the chain under control allows the rider to be more closely connected to subtle suspension action.
Race Proven
"I've been loving the Chain Damper! I find it better over other products on the market due to the stiff springs inside eliminating any drivetrain feedback and feeling
of the hub engagement whilst riding rough sections"

EFBE Tested
Engineered to excel in the ISO 4210 fatigue test, the Chain Damper is built to handle all the force you can put through your pedals, whether you're on a power hour loop or racing full throttle on a big weekend between the tape.
“Even on my idler-equipped Kavenz VHP 16, I found the Rimpact Chain Damper to quiet chain slap even more completely than the Ochain. The extent to which the Chain Damper does away with chain feedback is eye-opening."
Frequently Asked Questions
How does the Chain Damper pair with a high/low engagement hub?
It works great with both! The Chain Damper works to reduce drivetrain feedback regardless of the points of engagement you have.
Does it work on a Hardtail too?
Yes, and arguably offers even more benefit due to the harshness of the solid rear end on Hardtails.
What Chainlines is it available in?
The Chain Damper is boost, T-type and DH compatible . Super Boost and other chainlines are mostly compatbible but you may need to adjust BB spacers to get the correct chainline. If you have a query regarding your particular bike please reach out and we can help confirm compatibility.
Why isn't there a travel adjustment so I can customize the feel?
Put simply, this would break the device functionality. Reducing the rotation angle by 25% will half the effectiveness of the device's ability to smooth out chain forces. We've precisely calculated the required rotation angle and spring rate to ensure maximum performance. You can however swap out between the two different spring rates included with your Chain Damper.
Which springs come preinstalled in my Chain Damper?
We ship the 30-32t units with trail springs installed and the stiffer springs included separately, with the opposite for the 34-36t units.
Is it compatible with my Chain?
As long as the chain is a 10,11 or 12 speed mountain bike chain that is also compatible with Shimano and SRAM 11-12 speed options then it will work.
Does it reduce pedal efficiency or create a spongy feel?
No, once the springs are compressed moments after applying pressure to the pedals, the chainring is engaged and there isn't any efficiency loss or noticeable spongy feel. You'll feel a soft top out on the travel of the ring when lightly engaging the crank but this serves to further isolate drivetrain forces and vibration.
Does it work with High Pivot Bikes and Idlers?
Yes. Idlers and HP bikes tend to have seat stays that sit super close to the chain undoing a lot of the advantages gained from reducing chain growth and shortening the amount of unsupported chain between the BB and the rear axle. If you watch high speed footage of these types of bikes you'll see plenty of chain slap and thus energy transfer into the frame and chain ring when riding rough terrain. The Chain Damper will still cut the majority of this feedback and noise from the drivetrain and produce a super smooth ride quality.
