I think I can do some of what Ken said. I think he means putting reverse force to the pedals. You are gonna need to anticipate and plan ahead to stop though. And, remember Ken has quite some years of training under his belt, and he is running low GI, right? I am running low GI too; I can "back pedal" my way down some hills without skidding or using my front brake. But I do skid.

I use whatever tires I can get at discount. Recently white Zaffiro's. Weird thing is Pasela didn't turn out well for me. That pattern is keep picking up sharp objects causing flats from the road. Which is why I don't prefer em, but people at LBS recommend em as skidding tires. It's no biggie for me but anyone got the same prob?
