The pump machine "AIR" in the original geometry with a longer front triangle will guide you perfectly through the most complex waves or berms, but it will not get lost even when flying over "table jumps" or small dirts. AIR TWO is built for weight and strength, so here we prefer the Rock Shox REBA lightweight, the Novatec D252SB-BO-AA 14T rear hub or the FSA Gamma Drive cranks. The AIR ONE is a cheaper version.
