Plastic retaining rings (2 pcs) for PilotOne

Plastic retaining rings (2 pcs) keeps the mapholder base tighty attached to the bars. There are 2 sizes, BIG (13,5 mm) and SMALL (12 mm), recommended number of teeth locked is shown at the first picture. If you hesitate which type is better for you, I recommend BIG ones, easily can be dragged across the clamps. If base is turning on the bars, put some plastic tape around the bars. Please specify which type of retaining rings you want in the "Note" box at the end of the ordering process..
