Shimano’s most premium low flange track hub needs no introduction, the HB-7710 is one of the world’s most popular hubs. The HB-7710 is NJS approved in the 36H version only. These hubs are amazing on the track or street, but when used outdoors require maintenance as they use non-contact seals and are a loose-ball (cup & cone) bearing.
