I have no idea what kind of road cadence. We bike in hilly terrain, and I'm always trying to grind up the next hill. Very few flats around here. Maybe that's why my stroke is so uneven.

Believe me, I try to spin as fast as I can. But I can't let go of the doorway for a second even without starting to tip. Maybe it will take a long time before I smooth out my pedal stroke. I guess in the back of my mind I worry that I may never be able to ride the rollers. Was hoping to hear ,"Oh yeah -- it took me two months, but I got it."
