You won't find a lot of spandex on fancy bikes here, or a throng of angry anarchic riders a la Critical Mass, we're mainly just regular bike riding folk. Here's what we envisio …

I'm starting this group for SF-based riders who want to share rides to various trails (e.g. Tamarancho, China Camp, Annadel, Skeggs, Wilder Ranch, Henry Coe, etc.), mostly for weekend rides, but I would also like to do some group after-work weekday evening or night rides in the area. There are already several Bay Area mountain biking meetup groups (and I belong to most of them) but I thought it would be good idea to have a resource for SF-based riders to use to organize rides starting form SF or …
