I ride in a lot of different groups. It doesn't necessarily matter if it's a group of racers or just fast, experienced riders. Some groups or individuals seem to have difficulties dealing with a pace line and rotating properly when necessary. Other groups seem to just be able to do it without any issues. Based on a number of things I've learned from a variety of riders I thought I'd try to dispense some of what I learned. I ride with a GoPro frequently just to see what I might catch. On this ride the riders worked well together and even in a strong crosswind the ride was fun due to everyone working together.
