As you ride, heat and fork movement build up air pressure inside the fork legs: the fork gets stiffer deep in its stroke. The bleeder screws at the top of the legs let you release this pressure.

Specifications

• Brand: KYB
• Manufacturer part number: KYB-4001001
• Supplied with its O-ring

When to replace it?

• Fork that gets harder as the ride goes on.
• Stock bleeder screw damaged, seized or leaking.
• You want tool-free bleeding with a simple press.

Check the fork and thread listed: the screw must match your fork's bleed hole exactly.

Fitting tips

1. Bike on a stand, front wheel off the ground, fork fully extended.
2. Unscrew the old screw and clean its seat.
3. Fit the new screw with its O-ring and tighten it gently: the thread is fine.
4. Bleed before every ride, with the fork cold and the front wheel off the ground.

Frequently asked questions

When should I bleed the fork?
Before every ride, cold, with the front wheel off the ground. Bleeding during the day also helps if the fork stiffens up.
