Yep I can relate to that without the short cranks, every so often I get cramp in my thigh muscles, this might turn out to be the shortest upgrade ever, shortest in time Iām talking about, time will tellI just bought those too (in silver, for my Reign E+ 1), and the difference is dramatic. First day using them I had terrible cramp in weird muscles of my legs at the end of the day, but since then, glorious! Enjoy
