I think you will find a home with the SLO Pokes. They are a bunch of strange riders themselves!!!

Actually in most road clubs that are considered to be "recreational" (stay away from "racing" groups) alot of different bikes are ridden. I would go to their website and let them know you are interested in riding with them and ask the question. It's not so much the bike as the speed. I think the 'Pokes ride between 10 - 14 mph (it should be listed on the website)http://www.slobc.org. If you can do that on your bike, then you are good to go.
