My sprinter bike. It has 84.4 and 90 gears. It's meant only for training. On the track and on the road as well (that's why there's a front brake with a clamp for easy removal).
My "stamina training" bike. Has wider bars, clinchers, road saddle and so on. Also the frame is an entry-level one. The gear is 72 inches. This one is used for long distance training and some (although rare) commuting.
Still need a beater fixed gear.
