Wolf Tooth Compression Plug with Integrated Spacer Stem Cap
Wolf Tooth Compression Plug with Integrated Spacer Stem Cap Info
Wolf Tooth Compression Plug with Integrated Spacer Stem Cap is a precision-engineered solution for setting proper headset preload on bikes with carbon steerers. Whether you’re building a road, gravel, or mountain bike cockpit, this compression plug provides a secure internal anchor point while maintaining a clean, refined front-end setup.
Designed specifically for 1 1/8" steerer tubes, the compression plug expands inside the steerer to safely preload the headset without damaging carbon fiber. Unlike a star nut, which should never be used in a carbon steerer, this system distributes force evenly and protects the integrity of the fork.
The included integrated 5mm spacer stem cap addresses a common requirement from fork manufacturers: the steerer tube must extend slightly above the stem. By incorporating a spacer directly into the stem cap, this design ensures proper clamping height while keeping the cockpit streamlined. Available in multiple anodized color options, it also adds a subtle visual accent to your build.
