Compression Plug with Integrated Spacer Stem Cap

The Wolf Tooth Compression Plug provides an anchor point to set the headset preload on road, MTB, or gravel bikes with carbon forks—essentially securing everything on the steerer tube. A stem cap with a 5mm integrated spacer is included, which is important since many fork manufacturers require the steerer tube to extend above the top of the stem. It is available in eight color options to add some style to your bike. Compatibility Forks with 1 1/8" steerer tubes. Designed for carbon steerer tubes; also works with metal steerer tubes with inner diameter from 23.5mm to 24.5mm. Never use a star nut on forks with carbon steerers.
