![]() ![]() A set of kelly's take offs (or suntour command shifters) or even shifters mounted beneath the tops suits me well enough, and are easier (require less force at a stupid angle) than STIs. ![]() I don't think they are terribly ergonomic to use (and I never have done, even though I've owned bikes with them fitted for 25 years or more). If you want to retain the separable nature of the moulton, you either need to make the cables etc QD from the handlebars, or use a plug and socket inline.įWIW I wouldn't choose Di2 (or even STis come to that) the former is more complexity for little gain, and the latter effectively presupposes that you spend most of your time riding on the hoods, if the gear controls are to be 'handy'. I don't think a spliced joint in the cable should be a show-stopper it just needs to be waterproofed and mounted in such a way as it isn't flapping about. I had a bit of a mishap with the first battery which I broke when I removed it from the seatube rubber, it is quite amazing how little is inside the casing, the actual battery is the size of a single AA, which really amazes me how long it lasts for. Even after last weekends london orbital - a total shift fest of short sharp hills, which I ece'd out and, back to make it just under 600km for the weekend, the battery showed at 85% when I got home. After the LEL - which I did not connect the bike to a charge once, the battery showed as still having 60% power on the etube app. With regards the battery, it is internally mounted in the seatpost, I have never experienced any issues with it running out of power on a ride - even so I carry the charger and, a power pack just in case. obviously the gearing would alter on the moulton but, I'm pretty sure there must be chainrings to suit. My two penneth worth :- I run ultegra Di2 on my Genesis Datum, it has compact 12-34 cassette, this proves ample for most things but was defeated a couple of weeks ago by a couple of the climbs on the Knock ventoux. Interesting thread with a wide variety of views / responses, some good some less so. The challenge there is getting more power into the battery pack as it does need more than the Di2's 1hr.įor splitting the bike with internal routing an appropriate choice of cable lengths and junction box although slightly more expensive would make sense preventing the cables and junction box from disappearing down the tubes may be a tad trickier! I've had a full charge from my PowerMonkey Explorer 2 it used about 10% of the battery capacity IIRC, which is less than my Wahoo takes (about 20%) and way less than the Lezyne Super GPS (about 60%) but since I've had about 1500km worth of gear changes with a mix of hilly and flat, and my tendency to use all available gears the chances of running out of gears during an Audax that doesn't involve more than 1hr charge time snoozing or sleeping seems minimal. ![]() When it comes to charging the Di2 a suitably beefy USB battery pack is able to charge it, didn't think it was possible while moving unless you go without gears but since I've got the bar mounted Junction A it's a bit trickier to hook up to the battery pack. I would not trust such an unsupported (as in the cable not being attached to anything within the frame) joint on multiple 200km rides let alone a 1000km brevet (and I am quite handy at the soldering cables game!) I would caution against this, the cable is of a construction that is similar to a silicon coated headphone cable so rejoining for a reliable connection is going to prove to be a very skilled job resulting in a joint which is probably larger than the cable end connector. This thread is the second time I have seem people advocate cutting a DI2 cable to allow fitting. You do need to carry the charger block with you to do this (it is just a USB device but slightly bulky ![]() In terms of charging, I just topped mine up once during LEL - it took about an hour and I did it whilst moving. the traditional under the stem mount or as a bar end plug or as a special 'in frame' mount, the later needs a frame with a specific shaped cut out in it.) 4 port or 5 port) or mounting configurations (i.e. There are a few options around "Junction Box A" some are just a variation on the number of switches that can be connected (i.e. You can put the battery wherever within the frame that suits your needs, multiple 4-way junction boxes could be used (they are just a 4 port common connection with no electronics inside them) (Ignore the WU101 unit if you don't want to connect the DI2 to your Garmin Edge or update it through bluetooth?) You won't be able to charge the internal battery separate from the bike without a set of almost the same cables you already have on the bike! (So external charging would require a junction box A (where the charger plugs in) and then a cable between that and the battery. ![]()
