RockShox Metric Coil Spring

Spring rate selection is highly personal and depends on your rider weight, bike leverage ratio, and preferred sag. Generally, a 550 lb spring is a mid-to-firm option, but you should consult your specific bike frame's suspension setup guide or a suspension calculator to ensure it matches your sag requirements.

This spring is designed for specific metric shocks with a 134 mm length and 47.5-55 mm stroke range. Always verify your shock's stroke length and the required spring length before purchasing to ensure proper fitment and safety.

No, the Electric Red finish is purely aesthetic. It offers the same durable steel construction and consistent spring rate performance as other standard RockShox coil springs.

Coil springs like this one offer a more linear suspension feel, which many riders prefer for better small-bump sensitivity and consistent performance during long, rough descents. Unlike air springs, they are less affected by temperature changes and friction, providing a predictable ride quality throughout the stroke.

Yes, installing a coil spring is generally straightforward if you have the correct tools to remove your shock from the frame and adjust the preload collar. However, ensure you have the proper spring compressor or the ability to fully unload the shock to swap the spring safely.
