  1. Hi, i would like to know if is best to have 4iiii powermeter dual side on dura ace or inspider from rotor 24mm
    i have a trek madone slr disc BB90 with dura ace 9100 crank. Thanks

    1. The black bands are o-rings. They go around the outside of axle and sit against the crank arm after the axle is threaded into the cranks. I believe the axle is different size diameters.
