What is the purpose of Echelon formation?
In road bicycle racing, an echelon formation is a diagonal line of racers, which allows cooperative drafting in crosswinds. In sheet material response to shear stress it is typical for a series of echelon cracks to form. This is commonly seen in asphalt roads subject to shear stress imposed by aseismic fault creep.

What is an echelon in cycling?
Echelon. The echelon is where riders position themselves at slight angles alongside each other, to ensure they get the best protection from a crosswind and preserve energy for later in the race. Cyclists riding in an echelon formation.
