The SKS Airchecker. SKS developed and designed Airchecker, a digital gauge with a completely new design, especially for cycle tyres. Due to its swivelling Duo Head, the backlit display with its XL-format digits is always easy to read. The display can also be switched from bar over to PSI. The reduction button allows the pressure to be regulated exactly to required values. Includes neoprene bag for safe storage in jersey pocket or seat pack.
