This year I am riding outside during the Chicago winter season, as opposed to riding attached to my Cycleops. I purchased all the needed gear. I am fortunate to live one block from our eighteen mile long paved lakefront trail. It is treated like a street. It is plowed and salted as soon as it snows. Occasionally there will be ice patches a few feet long sometimes longer. I am experimenting on how to ride through theese patches also during the summer when it is windy there will be sand on the path. a) pick up a little speed and freewheel through with my pedals at 3 and 9 oclock and I shift my but all the way to the rear of my saddle or b) shift to a lower gear and "power my way through" any of you have this situation during theese cold months?
