It has to be some kind of built in system that manages the tire pressure. It could be any system used in the past, like that used in 2023, or some other system. It has to be either automatic or controlled by the rider, something that lets them change the tire pressure while still riding. Carrying a CO2 does not count.
Has to be at least two riders on the team using it. One single rider is just an individual and won't count.
DSM is also not using their one (I heard).
@Checktaschu At least two riders. One single rider won't count. If it's just one, that's an individual. Two are a team.
