The Ultegra Di2 components and all the other electronic necessities total $1,595, or $2283 for a complete Ultegra Di2 build.  The mechanical Ultegra 6700 group retails for $1,500.

For comparison, Dura Ace Di2 costs $2749 for the electronic necessities and $3927 for  a complete build. A complete mechanical Dura-Ace 7900 group costs $2690.

Reports from users is that Dura Ace Di2 certainly works. It is an engineering marvel and just a joy to use. The automatic trim of the front derailleur is certainly a nice advantage.  But the real roadblock is the price  of $3927.   So Ultegra Di2 at $2283 can really get this cool stuff in the hands of consumers.  Instead of going mechanical Dura Ace, the consumer now has a choice of going with Ultegra Di2.

Riders will have to pay a weight penalty, as the new group tips the balance, according to Shimano’s claimed weights, at 2,458 grams. Dura Ace Di2, by comparison, weighs in at 2,108 grams.

Some individual pricing of Ultegra Di2:

Shifters: ST-6770 Dual Control Levers -$444.99

Rear Derailleur: RD-6770 – $339.99

Electric Cable Junction: SM-EW67-A-E – $404.93

    I still don’t see the point of this for the casual/recreational rider. if you have a properly maintained bike, you aren’t going to encounter the need for any of this. i have a friend with DuraAce Di2, and the only thing he can tell me is that the shifts are a little faster and he never misses a shift. Since i don’t race, i don’t see either of those things being a \must have\. i rather keep my money, and keep the weight off the bike, than have the few benefits that this brings.

    also, why’d they change the color of the rear derailleur? this will probably keep people from upgrading, because of the mismatch between the \old\ Ultegra 6700 and the \new\ 6700. doesn’t make sense to me.

    One advantage to either Di2 system is not having to adjust the derailers due to cables that stretch over time every year.
