SW-R600

Brand: Shimano

Di2 satellite switch known as the « climbing shifter », sold as a single unit rather than a pair — its distinctive trait in the range. One captive E-Tube SD50 connector, free positioning on the bar, 19 g. Shimano lists it as reprogrammable through E-TUBE PROJECT. It left the specifications catalogue after the 2023-2024 edition while remaining in the 11-speed Di2 compatibility tables.
