The Shimano SM-SC70 wireless harness connects the computer controls that are mounted on the STI shift levers to the Flight Deck computer head. The harness contains both right and left controls, the central mount, bar clamp and wireless fork sensor.
The controls mount to the each lever and attach to the central unit via small wires. The central unit is then attached to the bar with the included bar clamp. The SC-6502 computer head (sold separately) is then attached to the central mount. The wireless fork sensor mounts easily to the fork for wireless transmission to the Flight Deck computer head.
The SM-SC70 is compatible with Ultegra 6600 and Dura-Ace 7800 10 speed STI levers only. SC-6502 computer is sold separately.
