It's funny how everyone does it differently!

I was told to unclip at 12, so the clipped in foot down at 6 puts you in a more stable position. If you unclip at 6, are you then doing a half stroke to get that foot up to 12 before you put your other foot down?

I've always unclipped at 12. I also unclip my right foot, which is the dominant leg, and this was a hot topic of conversation on some group rides, lol.

WHatever works for ya!
