TMD
The TMD sits inside the steerer tube and is meant to calm vibration and sharp energy spikes before they reach the riders hands and forearms.
Rimpact now frames the system more as an energy-smoothing mass-damper approach than as a fixed-frequency trick. It installs in the steerer, works with single- and dual-crown forks, and does not rely on a classic tuning menu.
This matters for fast DH and bike-park setups because the goal is not tire protection but a calmer front-end feel and less rider fatigue. Conceptually, that is different from a classic tire insert.
TMD is most useful once your base setup, cockpit position, and suspension are already sorted. If the front end is fundamentally unsettled, it will not replace proper tuning.
Riders who already have suspension setup under control and now want to work on hand fatigue, grip feel, and calmness at the cockpit.
