6. Suspension stiction is a big deal


Short answer: It’s not, and it’s certainly not worth the thousands of dollars some riders spend on special coatings.

To visualize stiction, try this: Think of a fishbowl full of water. When you go to slide it, the water sloshes. Once it’s moving, changing the rate of movement doesn’t cause it to slosh nearly as much. The same is true of suspension components. Stiction plays a role in measuring sag (which is why, historically, riders have been instructed to take the average of two or more measurements) because the movement is very slow. Similarly, stiction feels like a big deal when reassembling your fork because of the effort required to compress the components when they’re empty. While it may seem like a lot when working with your hands, compared to the forces encountered on the road, the force values are extremely low.

Sorbo says that stiction behaves in the exact opposite way of air resistance. The faster you go, the less stiction affects things. Stiction only really affects things when they are stopped and you’re trying to start them moving. On the road/track, the forces are much higher and the force required to overcome stiction is comparatively so small that Sorbo says it doesn’t matter.
