“the slimness of them really helped with pedal strokes at the top and bottom of the stroke.”
With a normal flat pedal there is a dead spot at the top and bottom of the stroke due the body, with the Crampons, because you are so close to the axle you do not have to rotate the body with your foot, if you know what i mean?
As for grip, many say they are very good, whilst other don’t like them, just like anything i suppose.
I am not sying they are better than anything else, just that they offer a very unique design, though i do understand they are expensive 🙂
