Argon 18 Cap Plug Info
The Argon 18 Cap Plug is a genuine replacement part designed to fit Argon 18 stems, keeping your cockpit clean and complete. Whether you're replacing a lost or damaged original or finishing a fresh build, this small detail matters — an open stem cap looks unfinished and can allow debris into the steerer.
A direct OEM fit means no guesswork. If you're running an Argon 18 stem, this is the correct plug for the job.
