Suspension advice: Nitride coating on forks

1 of 1

Q. What is nitride coating and what does it do for your forks?

A. The structural elements of a fork leg are two precision-made tubes, one sliding inside the other. When the forces of riding are applied to these tubes their tendancy is to bind together causing static friction or "stiction".

A titanium nitride coating has lower friction than one plated in chromium which helps reduce the stiction making the suspension more "fluid" in its operation.
