Spotted outside the team bus at La Vuelta, Shimano’s forthcoming Dura-Ace group—the R9300—appears to be 13-speed and retain a front-derailleur option, with derailleurs wired to a central battery in a semi-wireless setup rather than full wireless; the imagery also hints at a new freehub and possible frame compatibility questions, though sources say a full release isn’t imminent this year.
Cyclingnews reports a prototype Shimano Dura-Ace R9300 groupset has been spotted on Alpecin-Premier Tech bikes at stage 1 of La Vuelta a España. The photos indicate a 13-speed rear cassette and a redesigned shifter with a protruding thumb button, with a semi-wireless setup (shifters wirelessly communicate to derailleurs via a battery in the frame) rather than a fully wireless system. The leak suggests a new freehub body will be required, alloy cranks similar to current designs, and potential 1x compatibility, though exact cog sizes and final specs remain unconfirmed.
