Riding some sweet single track this morning, mostly in high gear. Also tried some rather unorthodox static “toe” & “hand” shifting while balancing in static position. Shifting is normally done while pedaling, by "swiping" the shift buttons with the sides of your shoes. Your feet don't change position other than pivoting your heel inward a bit to engage the shift button. It goes form normal 1:1 direct to 1:1.5, gaining 50% in effective wheel size. It's a BIG jump up in gear ratio!
