Rimpact Tuned Mass Damper

Rimpact Rimpact Tuned Mass Damper is an internally installed tuned mass damper designed to reduce trail-induced vibrations transmitted through the fork steerer. By targeting high-frequency chatter, it helps decrease hand and arm fatigue on long or rough rides while maintaining the familiar feel of a standard cockpit setup.

Built around a compact 97% pure tungsten mass, the damper uses low-friction IGUS self-lubricating bushings to let the mass move freely between two springs. Three included, frequency-calibrated die springs make it easy to tune the response to rider weight, terrain, and ride style—without external add-ons or changes to bar height and fit.

• Internally installed steerer damper - Targets vibration at the source for a cleaner cockpit and consistent steering feel
• 97% pure tungsten mass - High-density material enables effective damping in a compact package
• IGUS bushings - Low-friction, self-lubricating interface supports smooth, repeatable mass movement between the two springs
• 3 spring options included - Calibrated die springs for frequency tuning: blue (light), yellow (medium), red (heavy)
• Broad steerer compatibility - Fits aluminum or steel steerers; tapered or 1 1/8"; single or dual crown; oval or cylindrical (requires 190mm+ steerer length)
• Weight - 420g
