Zipp has been working hard tailoring its range of components, and nowhere more so than with the new Shiftboss, retailing at £190 for Shimano-compatible only.

As S-bend extensions can only be cut back a diminutive amount due to the shifter boss wedge, often the extensions are still too long and big hand movements are required to shift.

To resolve this, the Shiftboss replaces the expander wedge on Shimano?s bar-end shifter, saving 80g, adding internal cable routing, and vitally, reducing the shifter reach by 30mm, as the extra length after the S-bend is no longer needed.
