Where I live, I’ll rarely have more than forty feet of my 15-25 mile ride be ice. I stay in high gear most of the time - low torque advantage makes for very little slipping. I’m leaning far back enough that I’m pulling on the bars and most of my weight is pushing my soft-compound summer rubber in the rear to conform to whatever shape the ice may have going on. I’m loose and ready whenever it’s below 36 Freedoms. Little patches of ice are usually less than one full crank rotation long and momentum typically carries me through them.
I’ve fallen a lot over the decades. I flop instead of slam. I roll instead of splat.
