Shimano Dura-Ace groupset spotted at Vuelta a España

A new Shimano Dura-Ace groupset, potentially the R9300 model, has been spotted being used by the Alpecin-Premier Tech team during the Vuelta a España. The equipment was visible near the team bus as riders prepared for the first stage of the race.

Observations suggest the new groupset may feature a 13-speed cassette, which would place Shimano alongside Campagnolo in offering a 13-speed road groupset. This configuration aims to reduce the jumps between gears, providing smoother transitions. Other potential technical updates include integrated satellite shifter hoods and a possible new freehub mechanism. The setup appears to maintain a semi-wireless functionality, following previous leaks and the recent launch of Dura-Ace R9370 wheels.
