The Dutch or Flemish word “Waaier” is a certain stratiegic formation that riders do in a group. For example, you have a breakaway of six riders, the person who is setting the pace at the front will take a pull and then relax and draft in the back of the group, untill they have to take another pull. – Basti
The Dutch or Flemish word for echelon: a staggered, diagonal formation that provides shelter from crosswinds. Riders will take turns riding in the leading, windward position and then drift away from the wind and towards the rear, while their companions advance towards the wind in the draft behind them, until it’s their turn to take the lead.
