How do I determine the stroke of my shock?
Measure the distance from the shock's main body to the end of the shaft. You can also find this information on the manufacturer's website. Look for figures like "205x65mm," where 65mm is the stroke. Depending on age, brand, and model, some shocks may be marked differently, so check accordingly.
How do I determine my wheel travel?
Wheel travel is the distance the wheel moves from full extension to full compression. Refer to the manufacturer’s website or measure the distance yourself using the relevant guide.
What do spring rate figures mean?
Spring rate is the force required to compress the spring one inch, measured in pounds. A spring marked "450x65mm" means it has a 450-pound spring rate and a 65mm stroke. Softer springs have lower rates (e.g., 350) compared to stiffer ones (e.g., 450).
What sag should I run?
Sag recommendations vary by discipline: XC (20-25%), Trail (25-30%), Enduro (25-35%), DH (30-40%). Adjust based on personal preference, as the optimal sag is ultimately up to you.
What spring size should I run?
Your spring stroke/travel should be longer than the damper's stroke/travel to prevent the spring from bottoming out (coil bind) before the damper does. Always use a spring with a stroke length equal to or greater than the damper stroke length.
How much preload should I run?
For optimal performance, do not exceed 1-2 full turns of preload from the moment the preload collar contacts the face of the spring.
What if I'm doing drops or bigger jumps?
For drops, use a spring rate 10-15% higher than recommended for 28% sag. You might need two springs: one for 'normal' riding and another for drops. Consider your fully kitted weight, including gear and backpack.
