Airmousse combines a high concentration of Nitrogenium into an incredibly tough micro-matrix of proprietary elastomers. This eliminates the dead feel and provides a much more lively, lighter and traction enhanced feel from the very first ride, as they do not need a break in period. Additionally, our proprietary formula and manufacturing process provides a mousse that will last up to twice as long ?over 12 months? at a much lower cost. Packaged comes with 85g tube
