I believe the proper terms is: Stiction. This is when your fork isn’t buttery smooth, instead it sorta grabs or sticks when you’re squishing down on your fork or rear suspension. If you’re having issues, try this great product, it’s made by Finishline and it’s stanchion lube. Makes your fork and rear shocks super slippery.
I noticed that my KHS Lucky 7 was experiencing stiction the fork. This is common on Marzocchi forks, so I busted out my small bottle of this fancy lube and went to town.
Apply some on the felt pad that comes with the kit.
Then liberally apply on stanchions. After doing so, cycle or squish your forks up and down to ensure that the lube gets all the way down into the seals.
That’s it! This should help your stiction issues on your fork or shock.
