All STI Dual Controller feature an 18mm higher brake lever pivot axis, a curved lever shape and non-slip textures on the contact surfaces for optimum grip even in the roughest terrain. The STI line up of the GRX family is complemented by the 1x11-way RX800 and RX600 STIs for the left without switching or DSP functionality, including the 1x11 Di2 version (ST-RX815), whose three switches (two on the side and one on the top of the cap) can be used to operate 3rd devices such as compatible lights or computers.
