he hi-lo is back and better than ever with the new unisex VO2 S 100X BOA®! To bring an added element of speed and a different skating position this skate’s wheels are in a hi-lo configuration with 100mm wheels in the back and 90mm wheels up front, all with the ILQ-9 Classic Plus bearings. Built on the single-sided VO2 S Frame, the VO2 S 100X BOA® is fast, responsive and absorbs road vibration.
