Rimpact

3-Bolt SRAM Chain Damper

Rimpact 3-Bolt SRAM Chain Damper is a direct-mount drivetrain add-on designed to reduce harsh drivetrain feedback by isolating the rider from spikes in chain energy. By smoothing peak chain forces through a precisely engineered, limited angle of rotation, it helps calm impacts transmitted through the chainring/crank interface—useful for riders chasing a quieter, more controlled feel under load in rough terrain and high-torque situations.

• Chain-force damping mechanism - Captures a precisely calculated angle of rotation to smooth peak chain forces and reduce drivetrain feedback
• SRAM 3-bolt direct-mount interface - Compatible with SRAM 3-bolt direct-mount crank setups for a clean, integrated fit
• Multiple X-ring seals - Creates strong resistance to dirt and water to protect performance in wet and gritty conditions
• 7075 aluminum construction - Delivers high strength-to-weight for durability without unnecessary bulk
• 230 g claimed weight - Adds damping function while keeping overall system weight in check
