Retrospec Amok bike in good condition, selling for a friend who moved out of town. It's a single speed, not fixed gear. Asking $300 o.b.o. Cantilever brakes, flat handlebars with a backward bend (not sure what that's called). I don't know the frame size but it fits me pretty well at 5'11" (happy to take whatever measurements you need). Used but in great shape. Quick release on both tires. Also has sweet Shark Attack sticker.
