Another post about group rides as well as a recent ride with just three bikes got me wondering, what signals do you use for each other? When i went with three bikes we really just winged it (not very well either). For example when someone needed to pull off for gas we just hoped the others noticed. Flashing brights didn't always work as a moving bike gives the impression the brights are being flashed as it bounces along. There must be some standard signals seasoned groups riders use.
