Can someone clue me in on this??
One of the Tri Forums I read mentioned this "gesture" but I have never heard of it.
I do lots of club rides, and we do all types of pacelines....single paceline, double paceline, rotating (in a circle) pacelines, even echelons sometimes.
Anyway I am clueless about this "elbow flick" but the tri guys/gals say it's common practice.
I just pull over when my pull is up, or in the case of a circular rotating paceline, when there's room for me to slide over.
