This tool is inserted into the handlebar instead of a handlebar plug.

That way, you always have tubeless tools with you and you do not have to think about remembering it.

The holder is made of aluminum.

3 different O-rings are included so it fits in most handlebars.

Red: 17.9-19.1 mm inner diameter.

Blue: 18.5-20 mm inner diameter.

Green: 19.1-20.9 mm inner diameter.

The tool protrudes 5 mm from the handlebars when stored.
