Shimano Ultegra Di2 SW-R671 TT Shift Switch Set
With the Shimano Ultegra Di2 SW-R671 TT Shift Switch Set there is no need for triathletes to choose a shifter position when Di2 multiple shift controls are made simple and possible. Use Dual Control levers on the base bars and satellite controls on aero extensions. The controls work in conjunction with one another from base bars or in the aero position. Multiple control positions mean shifts are always close at hand. The SW-R671 TT Shift Switch Set is compatible with Shimano Ultegra 6770 Di2 10 speed, along with the Shimano Dura Ace 9050 Di2 11 speed group sets.
*DOES NOT INCLUDE BAR EXTENDERS
