Aimy is a small but nice gadget, particularly interesting for all those who like to work on their bicycle. Taking off the stem and handlebars usually makes you wish you had more than two hands to do everything you need to do and at the same time keep the fork from sliding down through the head tube. Instead of simply sliding onto the head tube, like a normal headset spacer, the Aimy is fixed onto the head tube, preventing the head tube from falling through the headset once the stem is removed. Convenient, right? Beyond that, Aimy acts as a regular headset spacer, measuring 8mm tall and weighing 8g. Plus, you can use Aimy as a reference to easily readjust your handlebars for perfectly straight alignment in case your stem has rotated for any unfortunate reason. Aimy is locked and will not move, even if the stem does, and as long as you have previously aligned the Aimy's locking slot with that of the stem, you have a simple but effective indicator for the straight handlebar position.
