Technical information:
So that the spoke calculation for the wheel construction works already in the planning phase, we give the ERD dimension in the respective descriptions. The ERD dimension given by us is the diameter over the ends of the spokes, which should ideally be at the bottom of the nipple slot. The advantage is that the nipple seat is included in the spoke calculation and the results are more precise. Please search for a calculator that can calculate with this ERD dimension.
