Gebla Rohbox ShimKit A21 special order 2 x M4 x 20A modification kit that allows you to use Shimano Hydraulic drop bar shifters to operate the Rohloff Speed Hub. The Gebla Shimkit is a unique and creative way to modify drop bar Shimano Road or gravel shifters to operate a Rohloff internal geared hub. Previous versions of the Gebla only worked with Sram Double tap shifters, so enabling Shimano compatibility is a huge win. It creates by far the neatest way to run a Rohloff Hub and drop handlebars.
