    Long Distance cycling & Ultegra Di2

    I'm buying an Orbea Orca Bli2 which has Ultegra Di2 shifting and I'm worried about running out of battery life on long distance events. For example, I am starting to train for next year's Endless Mountain 1240 which is 770 miles. That's over all the estimates for battery life that I've heard.

    Does anyone do rides these lengths with Di2 shifting or know anyone who does? Does it last or do you have to replace the battery at some point?

    I think the 1240k EM is still going to be once every 4 years, and given my ride just ended that's quite often enough, thank you. Tom runs it as a 1000k on off years. I'm hoping to ride it next year so I can get my PA5000 award.

    From what I've heard, I wouldn't worry about battery life, but if you do you should be able to put a charger or a spare battery in your drop bag. I think one of the electronic systems would be really nice to have.

    I gather a rider on this year's London-Edinburgh-London had some issues with a Di2 bike, I forget the details although I think it related to the battery running down. If it's a concern take a spare battery?

    All of the bikes (and many other teams/riders) we used on RAAM this year had DI2 on them. We had no problems at all and I didn't here of any one else having one. As with anything when you start a big event, new tires, new cables, new batteries etc are all smart things to start with. The batteries are light and it's easy to carry a spare. Worst case you have a single speed for a while till you can get a new battery.
    It doesn't get harder, you just go slower.

    I have an ultegra di2. 18 months about 12K, charged it I believe four times. Should not be an issue.

    I was under the impression that it was annual. No matter, the 1000k is still plenty long enough. I'm feeling better about my choice to buy a di2 bike now. Most long rides loop back and pass by the start again anyway.

    There were several DI2 folk at LEL that had problems. Some were lack of battery charge but others were not diagnosed during the event.

    Did you have Ultegra Di2 or Dura-Ace? Dura-Ace has 2x the battery life (according to Shimano documents).

    Maybe I'm just an unintelligent, uninformed retro grouch who hobbles along on his classic bikes, but I don't understand the intrigue of a finicky battery-powered shifting system you can't tune or maintain without a dealer's diagnostics computer program when there are such amazing and reliable modern gruppos to be had cheaper. If given a choice between electric Ultegra and standard Dura-Ace, I'd go with DA any day.

    It's far from finicky. It runs perfectly. Every time I've ridden it, the shifting has been perfect and the front derailler is almost too good to believe. Shifting into the big ring is instant and works just as well under load! The durability of it is well documented and it's better over time than mechanical at holding perfect tuning. After mile 20,000, you will have had to tune it exactly ZERO times to get a perfect shift. On mechanical, the cables will stretch and wear out (along with housings, ferrals, etc). I've found mechanical to be more finicky and requires tuning every month to keep it shifting perfectly.

    Also, electric enables you to:

    1. Shift all gears at once with one button press if you want

    2. Change the speed it shifts at

    3. it auto-trims the front derailler based on your rear cog (and this covers all 11 cog positions)

    4. Change which shifter controls which derailler

    5. Change the number of gears it shifts on a button press vs hold

    NONE of that is even possible with mechanical.

    I *believe* the new Di2 does not require a dealer's diagnostics computer to program it - I think you can now do this at home on a Windows computer.

    We had DA on all four bikes.
