no, no, that's exactly what i'm saying. knowing your limits and working around them is crucial to how you ride. a person on a road bike with two hand brakes has to ride very differently than a person on a fixed gear with no handbrakes, and limits are there with both (i.e., a road bikes' brake pads won't do as well in rain, a brakeless fixed bike's braking system relies solely on the rider and his/her legs), and with both you have to ride appropriately.
my riding's fairly risky, but it's never without mind that i don't have hand brakes, and that braking with my legs has to be spot on or it's no good. it's all about how you ride, not what setup you rock.
