The pump inflates up to 8 bar/115 PSI. The pump handle is made of a soft rubber compound and is easy to grip. The combination of aluminium and carbon-plastic materials with SKS embossing makes the pump a necessary part of a biker with a sense of design. The inner pressure tube is made of carbon-reinforced polyamide. It has more durability than conventional plastics and the material provides a thinner wall density, making AIRFLEX a lightweight companion on all rides.
