SKS Airboy XL - it's the reincarnation of a very popular pump. Back in several variants and in full force, it offers fast, efficient blowing thanks to two pistons and two chambers. All integrated into a small, elegant pump that fits in a jersey pocket. Compared to the classic version, the XL version has a larger diameter. This increases the surface area of the piston and creates a greater volume of air when blowing. This makes the pump suitable for larger-volume bikes, i.e. mountain, trekking and cross bikes in particular.For all valve types Length: 179 mm Aluminum body Maximum pressure: 5bar, 73 PSI
