SHIFTERS SHIMANO ST-7970-L DURA-ACE 10X2

Shifters electroniques Shimano Dura-ace 7970 10x2. Shimano product code: ST7970PA. Although the entire 7970 package is heavier than the standard 7900, the STI Dual Control levers themselves will shed over 155g, meaning the additional weight is at least located down low and the bike might actually feel a bit lighter when swinging side-to-side. Button placement is analogous to mechanical units so shifting should be intuitive for current Shimano users. As with the new 7900, the 7970 levers will also have a reach adjustment and will be compatible with the new FlightDeck computer (SC- 7900).
