SW-R9150

Brand: Shimano

11-speed Di2 sprint switch, sold as a pair, taped under the bar tape in the drops so you can shift out of the saddle without leaving the hoods. Each unit carries its own captive E-Tube SD50 wire and plugs into a free junction A port. Shimano quotes 12 g per pair and the buttons are reassignable through E-TUBE PROJECT. It remains usable on a 12-speed system through the EW-AD305 adapter.
