Some shocks have a much greater range of adjustment than others, some have a screw collar that is infinitely adjustable between its top and bottom limits while others have a collar that adjusts in steps, usually 5-7 steps between max and min preload. to set the correct sag you first need to measure the static sag. Stand the bike upright with its full weight on the wheels and measure the height of a fixed point on the bike above the ground and make a note of the measurement. Then sit on the bike and measure how much it sags and adjust the preload to give you the desired amount of sag.
Once you have set the sag you should then adjust the rebound damping if you can. To do this, stand the bike upright off its stand. Press down firmly on the seat and release, watch how the suspension rises. The suspension should take approximately 1 second to return to the original ride height and stop. If it rises past its static sag point and then falls again you need to increase the rebound damping and if it takes longer than 1 second or doesn't return to its static sag height at all then you need to decrease the rebound damping.
If you have compression damping then this is best adjusted to personal taste after riding. If the ride is harsh or jarring then you should decrease the compression damping and if the ride feels soft and wallowy then increase the compression damping. |
Thanks. I followed a slightly different approach, but it does make more sense to measure on its wheels.
The video I saw, the guy measured with the wheel off the ground, so its maximum drop.
Then he measured with the rider on the bike, pressed down, released and measured again. Then lifted up released and measured again.
He got the average from the lift and drop to get the average and took this from the maximum first measurement.
I would bet if I measured with the bike sat on its wheels, then me sat on it the sag is more like 25mm. Will try it tomorrow. |
