When I rode with a team back in the 90s, no one needed to signal in any manner other than look over one's right shoulder before pulling off to the right and drifting back. Nowadays, I'm really unclear as to what to do. When riding with guys who I just meet along a ride and we agree to work together, I do what I mentioned above but everyone just stays on my wheel. I don't think they're trying to avoid doing any work (well, I bet some are, lol). What are the universal, no question about it techniques to show you're done doing your part--hand signals, audibles, etc.?
