WOOdman Capsule PH Compression plug
WOOdman Capsule PH is a compression plug for 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. This obviously makes our Capsule series the best choice when using a carbon fiber fork.
Furthermore, the expansion force of Capsule opposes the clamping force of the stem, 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.
