Dura-Ace Di2 controls for a disc-brake TT or triathlon bike

This kit is the front end of a Di2 time trial bike in one order: Shimano's ST-R9180 hydraulic brake levers with a shift button in each lever for the base bar, the SW-R9160 bar-end switches for shifting from the aero extensions, both BR-R9270 Dura-Ace calipers already on their hoses, and the four E-TUBE wires that connect the levers and switches to the rest of the Di2 system.

How it wires up

Each lever and each bar-end switch takes its own EW-SD50 wire. On 11-speed Di2 the four wires run to a junction: the five-port SM-EW90-B under the stem, or an SM-JC41 inside the bar or frame. 12-speed Di2 uses EW-SD300 wires, so these E-TUBE parts join it through an EW-AD305 adapter.

Wire length depends on your base bar, extensions and stem, so the wire quantities and lengths above can be changed, and any part can be left out if you already have it. Rotors are not included. If you are not sure what your bike needs, ask us before you order, or book the fit-up with Tune Cycles.

Covered by Shimano's manufacturer warranty against defects in materials and workmanship. Normal wear (brake pads), incorrect installation, crash damage and modification are not covered. Warranty claims and returns go through Tune Cycles, and your rights under Australian Consumer Law are not affected.
