slow gear at high cadence is hard....its much much harder on flat pedals.
See! That's why! (see photo above - <3 my Deity pedals)
@BLT - I can go pretty slowly and maintain balance. Actually, I'm famous for this, because I'm so damn slow in general. My friend's "compliment" to me one day, while passing me - "Wow, I could never ride up these rocks as slowly as you do!" I just don't enjoy being in my granny gear.
