I was talking about S-A 3 speeds, so no fixed unless you do that insane sheldon mod. Although...
Some guy asked about flip flops and multispeed and stuff over in the mechanics forum the other day and I suggested some madness, which I may just have to build. 2 chainrings set real close, so that 9 or 10 speed chain barely clears, with a FD and a tensioner. Then set up a flip flop rear slightly offset so that the chainline was right in between the chainrings on the freewheel side, and perfect on the larger chainring on the fixed side. Then nail the chain length so that you can run fixed like normal with the chain tensioner out of the way. Bingo, fixed gear for fun, 2 speed freewheel for lazyness. Takes a FD and some cabling, but I suggested using one of those biga$$ single lever stem shifters off of a 1x6 suburban, wouldn't look any less clean than a 3 speed.
I guess maybe the narrow chain wouldn't be the best idea strength-wise, but if you started breaking chains you could just add a little space between the chainrings and go with regular stuff.
But yeah, I need some kind of beater multispeed rig because I'm looking at a long commute with a lot of wind. Definitely going to be some kind of frankenmonster, either something like this or a 3 speed rear with aero bars (bwahahahahaha...)
