The CBO Rear binding is a Mid Wrap boot. This binding is a more recreational fit than our Highwrap, easier to get in & out of. The Universal hole pattern fits all the new skis: HO, Radar, O'brien, Connelly, D3. The Old Kidder/ Wiley hole pattern fits all the older KIDDER skis as well as some of the EPs and other older skis.It also fits a lot of the GOODE brand skis that came fitted with OEM Wiley high wraps.
