🔄 Shimano Dura-Ace Di2 9200 Groupset
Shimano Dura-Ace R9200 Di2 is the 12-speed wireless electronic groupset at the pinnacle of Shimano's product range. Its semi-wireless architecture (electronic control, mechanical gear range sensing) was adopted as OEM by Trek, Giant, Specialized, Cannondale, and BMC for their flagship race bikes — confirming Shimano's dominance in the road racing OEM market against SRAM AXS and Campagnolo Super Record. The 9200 groupset weighs 2,055 g complete with Di2 derailleurs and a four-arm carbon crankset.
