Shimano Dura-Ace Di2 ST-7971 Reverse Shift/Brake Levers

When Shimano created their incredible Di2 digital shifting group, they didn't forget about Time Trials or Triathlons. The ST-7971 shift/brake levers are reverse levers for aerobar 'bullhorn' base bars. When paired with the SW-7971 shifters for aerobar extensions (sold separately), they provide the ultimate shifting control and precision without having to move hand and arm position. Shifting is performed by pressing one of two buttons on the inner face of the shift body. Braking uses good old reliable cables and housing with fancy unidirectional carbon fiber brake levers. Levers have reach adjustment for riders with smaller hands. The shift/brake levers are connected to the rear wire kit via the SM-EW79A-I front wire kit or the SM-EW79F-I front wire kit for Flight Deck compatibility.

116 grams/pair (weighed without included brake cables and housing).
