La Vuelta sighting hints at Shimano Dura-Ace R9300's 13‑speed future
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.
