The Marwe 2P (left side) and 2Q (right side) fork plates are compatible with Marwe 590XC/700XC/800XC Roller Skis. To equip one wheel, you will need two fork plates (one for the left and one for the right side). The 2P/2Q denotes the spare part number for this particular component, which can also be found on the exploded view drawings included with each pair of Marwe skis.
