Ohlins Mountain Bike Rear Shock Spring

This spring is designed with a 36mm inner diameter and a 177mm length. Before purchasing, verify that your shock's body diameter matches this 36mm spec and that your shock's stroke length is compatible with the 89mm stroke of this spring.

Spring rate selection depends on your total rider weight, your bike's leverage ratio, and your preferred riding style. If you are currently bottoming out too easily or finding the suspension harsh, you may need to adjust your spring rate; the 60 N/mm (343 lb/in) rate is a specific stiffness level that should be matched to your suspension setup calculator or manufacturer's recommendation.

While air shocks offer infinite adjustability, this high-strength steel spring provides a more consistent, linear feel that many riders prefer for aggressive trail riding. It offers a reliable, predictable suspension performance that doesn't change due to temperature fluctuations or seal friction.

The ability to choose springs in 4 N/mm increments allows for much finer tuning of your suspension sag and bottom-out resistance. This precision helps you dial in the exact feel you want, rather than being forced to choose between a spring that is slightly too soft or slightly too firm.

Yes, the advanced heat treatment increases the durability and fatigue resistance of the steel. This ensures the spring maintains its original rate over a longer lifespan, preventing the 'sag' or loss of performance that can happen with lower-quality materials after heavy use.
