Suspension
Why this could fit: The low-speed compression is too firm for the small chatter - open it a few clicks.
How to check it: Read the current value off the bike and compare it with the recommended one. Write it down before you change anything.
Smallest change: 1 click - clicks out from fully closed
Why this could fit: On air forks the air pressure is too high - reduce it; on coil forks address it via spring rate.
How to check it: Read the current value off the bike and compare it with the recommended one. Write it down before you change anything.
Smallest change: 0.1 bar
Tires
Why this could fit: Too much front pressure makes it harsh - lower the pressure for better small-bump compliance.
How to check it: Read the current value off the bike and compare it with the recommended one. Write it down before you change anything.
Smallest change: 0.05 bar
