• Di2 Ultegra 12 speed question: I know the shifters can be set up wirelessly or with wires. With wires, there is a claimed 50% increase in battery life.

    The claimed battery life is 1,000km so does this mean that the battery life with the shifters set up WITH wires is 1,500km?

    Sorry if this seems an obvious answer but I just wanted to double check. For long-distance riding/audax it seems well worth the hassle of setting up the wires for improved battery life.

  • I got 1800k out of my 11spd, both years I did TransAm. So, 1500k seems a reasonable value - sometimes more, sometimes less. I would definitely set mine up fully wired. You will give zero fucks about your 'clean cable routing' when your shifters stop working and you have no spare batts.

  • Awesome.

    I’ve never really worried about battery life on my 11spd Di2 as I never did a ride longer than 300km on it so just charged the night before. I did a 1,600km tour of Scotland over a week and just took the charger with me which is what I imagine I’ll do on 1,000km audaxes anyway.

    Wires it is!
