    At the touch of a button.

    While electronic shifting has several advantages for road bike, the advantages are even greater for TT bikes. Of course perfect shifting, no more dropped chains, and the lack of moving, oddly routed cables and housing are advantages for everyone. But the big difference between TT and road bike shifting is hand position. Not only is shifting on aero bars awkward and inconvenient, but there is a moment while you’re grip is changing that’s actually kind of dangerous. Shimano Ultegra Di2 Remote TT Shifters change all that with the touch of a button. Instead of adjusting your hand position on the bar, you simply touch the shifter button with your thumb, and it gives you a perfect shift every time. No more friction. No more cable adjustments. No more scary, out-of-control moments.

    • Safer, more comfortable hand position
    • Maintenance-free
    • Cleaner and more aerodynamic
    • Shift while coasting

    Love Di2

    • Familiarity: I've used it several times

    Can' t say enough good things about these. I have them installed on my TT tri bike and takes the thinking out of shifting. They package is great, less to think about and at a more reasonable price!

    Are these the SW-R671 shifters?

    Yes

    I have a 2013 venge with Ultegra di2 10 speed. The bike has a 3 port fitting and I wish to set the bike up as a TT bike. Can I do it with these TT shifters. Do the wires plug directly into the brake levers or do I need a 5 port.



    Many thanks

    Derek

    You need a 5 port junction box unless you have Dura Ace shifters or Ultegra 6800 or 8000 series shifters.

    Di2 Reference Guide
    Battery and Wires: Our Shimano Di2 packages are built for three standard configurations based on battery location and wire routing. First, you'll need to determine if your frame uses an internal or external battery mount, and whether the routing is either internal or external. Below is a guide for which battery, charger, mount, and junction boxes are required for your configuration.

    Battery Mounts: The SM-BMR2 battery mount is available in three configurations -- Long External, Short External, and Long Internal. Both Long versions are to be mounted using the bottle cage mounts, while the Short version is designed for Di2-specific frames with either a chainstay or down tube mounting location.

    Junctions: There are two junctions needed for completing your Di2 build -- A and B. Junction A, SM-EW90, is located at the handlebars and available in both three- and five-port options. The three-port option is intended for standard shifting with a left and right hand shifter. If you have the intention of using Shimano's satellite sprint shifters, or a combination of time trial shifters and shifter/brake levers, the five-port junction box will be the necessary selection.

    Depending on your frame specification, Junction B (SM-JC40 or SM-JC41) is located either internally or externally at the bottom bracket area. Accordingly, SM-JC41 is designed for frames with internal wire routing, while SM-JC40 is intended for external wiring options.

    E-Tube Wires: For your convenience, we've created wire packages for your Di2 build kit in the sizes Small, Medium, and Large. Below, you'll find which wire lengths are included in each kit. Additionally, we've recommended a kit size based on your frame size.
