Leaked images point to Shimano Dura-Ace 9300 13-speed details
New leaked pictures appear to show Shimano Dura-Ace 9300 shifters, rear derailleur and power meter as the top-end groupset update comes into view.

Shimano’s next flagship group comes into focus
New pictures posted on the Weight Weenies forum have given a clearer look at Shimano’s upcoming Dura-Ace 9300 13-speed groupset, according to road.cc. The images reportedly show new shifters, a rear derailleur and a power meter, adding detail to a product update that had already started to appear in public view.
The broader context matters more than the leak itself. Shimano’s top-end Dura-Ace platform is already expected to be updated, with the groupset seen at the Vuelta a España and Shimano having unveiled Dura-Ace 9300 wheels. Taken together, those signals suggest this is not just an isolated component sighting, but part of a wider rollout of the next flagship road setup.
For serious riders, the key point is that the performance ecosystem appears to be taking shape around controls, drivetrain, power measurement and wheels. Those are the areas that determine how a new high-end groupset will actually feel and function on the road, not just how it looks in launch material.
