Do you have two sets of touring boots? A race boot and a touring boot? A warm weather boot and a cold weather boot? Do friends or family sometimes ask to borrow your skis? And does this cause problems fitting your bindings when the boot sole lengths are different? If so, you need the 20-gram (the screws weight almost as much) ATK R01 Adjustment Plate, made specifically for Hagan Ultra World Cup bindings.
The R01 plates are ideal for infrequent binding length adjustments. They are also useful if you are remounting bindings and the old binding holes are in the way of the new ones. For those of you who think ahead, mount up your bindings with these plates and it will make it much easier to resell your skis.
The R01 lifts your heel binding by 5mm, and your boot by 5mm when you tour in flat mode. It is compatible with Hagan Ultra World Cup and ATK SL World Cup race bindings (and the Ski Trab TR-Race and La Sportiva RSR) but not all tech-style bindings.
