Gone for it and treated myself to ui2. Read all the reviews and it appears to tick all the boxes. Little or no maintenance, No cable stretch obviously, and bomb proof faultless gear changes. Not yet ready for pick up as the lbs is waiting for a chris king B/B to install that also is a treat. Would appreciate any views on this product both pros and cons.

    I am getting this with my new build. Went with the internal battery mainly because I didn't like the look of having the battery attached externally to the tubing.

    Unfortunately Kingstonian I did not have the luxury of the internal battery option due to the fact that my seat tube is aero.The battery is an eye sore it has to be said but hopefully the benefits will outweigh that issue. Cant wait. What bike are getting?

    Di2 is nice, but with the release of 6800/9000 I know longer find it to be the step up it once was (unless it's on a TT bike). CK BB is a waste of cash.

    The internal battery is tiny and would probably fit in your seat tube. Mine is aero and fits easy. The battery is only about 15mm thick. I'll check shortly

    As well as aesthetics, the internal battery also allows you to update, diagnose & programme the system using free etube software without having to spend an extra £150 on the SM PCE1 interface (you can connect a pc through the internal charger via the h/b junction box).

    cheers

    Not far off, it is actually 16mm at its widest point. Added a pic of it next to a pen for rough idea of size

    Ribble was cheapest when In bought mine. Came to about £78 and charger is another £50 ish.
    Bit more money than external but worth it imo

    I've had both and I can honestly say I much prefer the feel of mechanical groupsets!

    I've got both and much prefer the electronic shifting.

    For those weighing up the option of an internal v external battery, how does the battery cable hit the system? Presumably it relies on a hole in the frame to route the cable; does it also require the exposed multi-way bus connector, or is there a tidier means for internal battery set-ups?

    The internal battery wires run down the seat tube and then through the bottom bracket to a junction box in the down tube. This junction box connects the battery wire, the FD and the RD wires to one wire that runs up the downtube and out of the frame to a 3 or 5 port junction box that is attached to the stem. Recharging the battery is via the 3/5 port junction box on the stem. It's a pretty neat configuration.

    Page 16 of the shimano dealer's manual has a diagram showing the cable routing.

    not a chance. got DI2 and its exactly what i need. faster shifting, accurate, no chaindrops or wires to stretch and no chain rub.....

    Appreciate someone who is a good mechanic can get this set up on a mechanical system, but its so easy and the multi shifts are very nice.

    overal compared to my old ultegra which was 8/10 this is aroundabout 9.5/10

    This is because you haven't ridden DA9000. :P
