Five years in the making - one year longer than the usual product cycle - and following an intense period of speculation, spy shots and secret patents the Japanese component manufacturer has finally revealed the all-new 12-speed, semi-wireless Shimano Dura-Ace 9200.
Not only that, but Shimano has taken the highly unusual step of launching its new second string groupset, Ultegra R8100, simultaneously.
For the first time there will be no mechanical-shifting Dura-Ace option, and the same goes for Ultegra. Both are Di2 only, but it’s a new platform that uses wireless shifters, with new derailleurs wired to a battery in the seatpost. However, both groupsets have rimbrake options.
Those are just the headlines. Shimano is also promising its fastest and most reliable shifting ever, improved aerodynamics, incredible stopping power, the most advanced drivetrain yet and a redesigned wheel line-up.
What it’s not promising is lighter weight: it seems to have called a truce to the race to be lightest, with the new Dura-Ace R9200 groupset just under 100g heavier than than the previous generation. The new Ultegra is 300g heavier than the new top-flight groupset but costs around £1,000 less.
Shimano has broken the new groupsets down into chapters: shifting platform; control interface; brake system; drivetrain system and wheel system.
Shifting platform
“Fastest-ever shifting, absolute reliability, integrated design” are what Shimano is promising with its completely revised Di2 platform.
