Shimano displayed their latest Ultegra 6700 groupset with Di2 shifting today at DealerCamp in Deer Valley Utah. We’re told it’s one of only two Ultegra Di2 groupsets in the US at the moment, with full aftermarket rollout estimated for late 2011. So how does it shift? Exactly like it’s Dura Ace counterpart is what Shimano is telling us. Electronically, it’s identical to Dura Ace, where the difference comes in is the materials used. Because of that, Ultegra Di2 will come in about a pound heavier than similarly spec’d Dura Ace.
Where the Ultegra Di2 group stands apart from the current generation Dura Ace Di2 is the modular system the new electronic system utilizes. The new modular system uses identical cables, offered in 13 different lengths, to connect every aspect of the system to a single junction box. The junction box is available as either an externally mounted unit or internal, should one really want to go stealth. Front shifters, battery, and derailleur cables all meet at the junction box.
The new Ultegra Di2 group will also utilizes Shimano’s latest color option, Glossy Gray. Available currently on mechanical Ultegra, it’s a sleek looking finish in our opinion. Look for this new groupset to start showing up on 2012 bikes in the very near future.
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.
