Sonder Key

Classic 3 pronged hex tool in bright red so you can find it amongst your other tools.

Not that it is likely to be hidden at the bottom of your tool box. Just count how many bolts this tool fits, I found over 30 on mine - stem caps, stems bolts, handle bar mounts, axles bolts, derailleur mounts, seat post clamps, brake levers... the list goes on!

This Sonder hex key can also be used with other brands bikes!
