Thanks to Quentin I could have the look before everyone else at new Shimano 13-speed Dura Ace… and now you can too.
The prototype features a new 13-cog cassette, updated shifters and power meter, while Shimano appears to be sticking with its semi-wireless Di2 setup. The 13-speed cassette could also mean a new freehub standard, potentially with a 10T smallest sprocket.
Shifters seems new too with lateral additional button. Shimano hasn’t officially confirmed the groupset yet, but the future of Dura-Ace is already being tested at Canyon Alpecin PremierTech bikes.
