Wolf Tooth Components Compression Plug With Integrated Spacer Stem Cap Black, 1 1/8 Steerer

We use the Compression Plug With Integrated Spacer Stem Cap to properly set our headset tension on forks with carbon steerer tubes. Since you can't use star nuts on carbon, this nifty tool lets us easily dial in our tension, plus it even includes a stem cap to finish off the job and get you pedaling.
