Shimano Dura-Ace Di2 ST-R9250 2×12-Speed Shifters

The ST-R9250 Dual Control Levers are designed for the dedicated rim brake purist who refuses to compromise on shifting speed or weight. Unlike their disc brake counterparts, the R9250 shifters utilize a fully wired Di2 connection to ensure the slimmest possible hood profile and the lightest weight in the R9200 lineup. By eliminating the internal wireless transmitter and hydraulic reservoir, Shimano has achieved an incredibly compact ergonomic shape that provides superior hand wrap and control. These shifters offer the same lightning-fast 12-speed Hyperglide+ shifting performance as the rest of the Dura-Ace family, combined with the tactile precision of mechanical rim braking. For the ultimate lightweight climbing build or a high-performance rim brake restoration, the ST-R9250 is the gold standard.

Key Features

• Ultra-Slim Ergonomics: A significantly more compact hood profile compared to hydraulic versions, offering a natural and secure grip for all hand sizes.

• 12-Speed Hyperglide+: Optimized for seamless shifting under heavy pedaling loads, whether climbing out of the saddle or sprinting for the line.
