Gravaa, the manufacturer of the KAPS (Kinetic Air Pressure System), was declared bankrupt this week by a Dutch court, in news first reported by Road.cc and other media outlets.
Gravaa’s system enabled the user to adjust tyre pressures whilst riding, and we first reported on a Jumbo-Visma trial of the technology back in early 2023. The system, however, had been in development for several years before this.
