Our iS (Integrated Storage) solution for road and gravel riders, the iS Coupe cage is a top entry cage which can be mounted anywhere on the bike. The 10 function multi-tool is securely housed behind the bottle and features a special finish for higher resistance to corrosion. The tool itself has 10 function to help you get over basic road side disasters. The HP pump stands for High Pressure. Road pumps need high pressure capabilities at a low volume to enable you to pump to the higher pressures of road tires.
