Woodman Compression plug for 1'' Fork Steer tube

WOOdman Capsule PH is a compression plug for a carbon steerer tube and uses an expanding system with a larger contact area than a traditional star washer, it does not damage the internal wall of the steerer tube. Our Capsule series is the best choice when using a carbon fiber fork.

Furthermore, the Capsule's expansion force opposes the stem's clamping force, preventing damage to the steerer tube. Last but not least, unlike a star washer, the Capsule can be disassembled, making it possible to perform maintenance that would be otherwise impossible.
