Gebla Rohbox Shiftbox + Sim kit (Full set)

FULL SET! Not just simple shiftbox. Compatible with Shimano GRX 820.
The Rohbox is a shiftbox for Rohloff 14-speed internal gear hub. It replaces the original shiftbox allowing shifting with shifters other than the original Rohloff Twister i.e. on a dropbar the Rohbox can be operated by modified brake shift levers, or on a straight handlebar it can be operated by modified trigger shifters or even brake levers.

This new version now shifts 2 gear positions per lever movement.
