Because I work 45 hours a week as a starting point at my main job, then alternate Saturdays at an auto parts store. I can sneak in an hour of two wrenching in the evenings, and Sunday afternoons if I'm not mowing the grass which is growing like mad right now.
I do ride with a "vintage" bike group on Sunday mornings most weeks, but they are far from athletic, and as of now are mostly riding repop Pashleys and the like. I'll be lucky to break 11mph with that group, as I am the ONLY one who rides drop bars. The sad part is that the older bikes are mostly dept store bikes, and are in sad shape. Cranks tapping on kickstands, chains so dry they constantly squeal, low tires that they don't seem to notice. If they weren't friends I'd ditch them.
