WHAT IS
A TUNED MASS DAMPER?​
A commonly used device that reduces the amplitude and duration of vibrations in a greater system or structure.
Examples include:
-
Buildings and large structures, where earthquakes can shake the building apart.
-
In precision tools, where the rotating motors and cutting forces can reduce accuracy.
-
In spaceships and rockets, where high winds can create turbulence and rock the structure on the launchpad.
-
In ships to reduce the effect of rolling induced by the sea.
-
And famously used in F1 cars to control nose bounce when hitting curbs on the apex of corners.
In simpler terms, calms the bike, reduces fatigue and increases confidence.
How does this work for a bike?
The Mass is displaced from its resting position and runs on a shaft helped by linear bushings.
​
The Mass counters carefully chosen vibration frequencies that pass through the system by oscillating out of sync with these movements, effectively cancelling their influence out and reducing the chatter and impact forces felt through the bar.
​
This helps mitigate fatigue, smoothing out the ‘noise’ of trail chatter and large impacts, allowing the rider to focus on line choice, charging hard and having fun.
Does it make you faster?
Yes.
Our testing has shown that on average, riders are around one second per minute faster in blind, timed, A/B Placebo testing.
​​​​Whilst this might not sound like much, extrapolating this out on a long DH track or a full Enduro day this advantage can make the difference from placing
mid-pack to being at the sharp end of the finishers.*
*Results may vary depending on the track, rider, conditions and other variables. The above test took place over 6 locations, 6 riders and 120 timed runs ranging from 1 minute up to 6 minutes.

Suitable for
bikes with a steerer length
0f 190mm+*
Alu and Steel, Tapered and 1 1/8” steerers, single and dual crown, oval or cylindrical are all compatible.
​*Steerers shorter than this will need spacers above the stem to be compatible, please get in touch if you need further information.
Steerer must be 20mm ID at it's narrowest point
IGUS Bushings
Die Springs
2.17 times denser than steel, this material enables the design to remain compact and fit seamlessly into a steerer tube.
Allow the mass to move freely between the 2 springs and are self lubricating so do not need maintaining.
3 options include, all calibrated to carefully chosen frequencies. Fine tune to your liking.
3 spring rates for
Maximum Performance, No Matter the Trail
Light
Low energy, high frequency.
Medium
Final spring colour may vary
Heavy
High energy, low frequency
Designed for Steerers
​​​​​​​Igus polymer bushings allow the mass to oscillate freely between two equally rated Die Springs that feature a precise spring rate, calibrated to 3 carefully chosen frequencies. All this neatly packs into the space inside your fork steerer tube.
​
Mass is
critical
TMD features Tungsten Heavy Metal Alloy as it’s counter Mass, which has a density over 2.17x that of Steel.
​
This ensures the correct weight is used to counter the typical impact forces whilst being able to hide inside a fork steerer.
Total system weight of 420g.
