A neat little gadget, that is particularly interesting for anyone who likes to wrench on their bike.

Designed like an ordinary headset spacer, the Aimy slides onto the steerer tube and has a stainless steel bolt that clamps down so that the steerer tube cannot fall through your headset, once you take off your stem.

- Machined from aluminum
