Shimano has officially released the latest Dura-Ace Di2 9200 and Ultegra Di2 8100 groupsets, which are 12-speed, electronic only and semi-wireless.
The Dura-Ace 9200 and Ultegra 8100 groupsets share many of the same features. They are both available in rim-brake and disc-brake options, however they are electronic only. That means that there will no longer be a mechanical Dura-Ace or Ultegra groupset available, only Di2 versions. The disc brake versions of each groupset have wireless levers which results in a cleaner looking cockpit. The rim brake versions are still fully wired.
With the R9270 semi-wireless option, each shifter requires a CR1632 coin-cell battery. For those worried about battery life, each battery should last for approximately 1.5 to 2 years of use. Meanwhile the two derailleurs are wired directly into the central battery. The battery life of the main battery is claimed to last for around 1000km of riding and can be directly recharged from the rear derailleur.
The Dura-Ace 9200 and Ultegra 8100 groupsets weigh slightly more than their Di2 disc predecessors by approximately 35g and 11g respectively. The Ultegra groupset is approximately 280g heavier than the Dura-Ace groupset, however it will cost significantly less compared to its flagship counterpart by approximately £1,000/$1370USD/$1877AUD/€1164, which is a similar situation to what it has been in the past. Both groupsets are expected to cost slightly more than the current 9100 and 8000 groupsets.
The Dura-Ace 9200 groupset (Disc) weighs approximately 2438 grams whilst the Ultegra 8100 groupset (Disc) weighs approximately 2716 grams.
