Hi...Besides the PV Bike Chics, I found a few groups on meetup that have beginner rides every once in a while but I haven't had the time to go to any of the rides. I also joined the Bicycle Club of Irvine (they have a newbie clinic) but haven't been able to join them either. For now, I've just been going on the Bike Trails to seal beach on my own and have been working on riding clipless, speed, distance, etc. There's no hill work and the view can be a bit boring until you get to your destination! Good luck finding a group..maybe we'll end up on the same ride one of these days!
