Shameless Plugs from Arundel are an ingenious way to carry a selection of the tools you need on gravel exploration or bikepacking rides. The tool, plus 3 bits store right in the ends of your drop handlebar - completely invisible and unobtrusive until you need them. When you're at home, Shameless Plugs can be used like any other multitool for repairs.
The Shameless Plugs kit includes 2, 3, 4, 5, and 6mm hex keys, plus Torx T10, T15, T25, T27, and T30 bits; plus there's a JIS screwdriver built-in as well. Pick the 3 bits you need and install them in the "quiver" to take with you, then install on either side of your road drop handlebar with a clockwise twisting motion. When you need the tools, simply rotate counter-clockwise and pull to remove from your handlebar.
The bit receptacle is magnetic to prevent you from losing the bits on the trail.
Unused bits can be store in the included tin box display and storage case.
