It's nice to roll in a group of FGSS (pacing, hills, braking are all a bit different) so if you have a FGSS then bring that along. The idea is not to exclude people if they don't have one gear but to sort of encourage people to ride them if they have them. Lots of opportunities to ride with others on gears, fewer to ride FGSS hence the site etc. etc. but if you must bring gears don't let that stop you from coming.

Just don't ride like a dick ;)
