Andrews Individual Close Ratio Gear Sets

Andrews Individual Close Ratio Gear Sets

Complete selection of Andrews transmission components. Why Andrews transmission parts? Andrews gears and shafts are made from stronger-than-stock materials. They have heat-treated and polished surfaces where necessary for smoother and faster shift operations, which results in much longer durability of all transmission components. It's hard to believe there is such a big difference between Andrews gears and others until you ride a bike with these products installed.
