Wheels that have been off a track or a beach come off the stroller dirty, and they mark car boots and carpets. This bag holds them, so the load area stays clean and the wheels are not rolling around loose in the back.
It is sized for the big rear wheels and will take the smaller front wheels and their forks as well, which means the whole set of spares travels in one place. A side pocket holds the axles, so the pins that are easiest to lose have somewhere to live.
Carrying straps let one person move the lot in a single trip, which helps when a carer is already handling the stroller and the client.
