I'm still pushing the same gear, didn't get a chance to change it. Man, I am *SORE*. My calves, quads, even my hamstrings hurt. I never would have expected that, since I've been riding SS all winter with pretty much the same gear, on the same bike. The "engine braking" part really takes it out of you-like doing a set a hack squats at every light. I am finding I use my front brake very little, but I can't imagine ever taking it off.
