• Split type 7075-T6 aluminium crown race for simple, tool free installation
• Max headtube length to get a full 1.0 degree change is 126mm due to space for bearing offset internally - above this length the alternative EC44/ZS56 would be the preferred option as it allows the upper bearing to be offset externally - The ZS44/ZS56 combination is only available in the 1.0 degree option.
