Shimano Dura-Ace ST-R9270F-L Di2 Shift/Brake Lever with Caliper - Left/Front
What Does the Shimano Dura-Ace ST-R9270F-L Di2 Lever with Caliper Include?
The ST-R9270F-L is the left-hand Di2 shift and brake lever from Shimano's current flagship Dura-Ace R9250 groupset, sold here as a complete unit with the integrated BR-R9270 hydraulic disc brake caliper. This is the front brake side, combining electronic shifting for the front derailleur with hydraulic disc braking in a single lever and caliper assembly. The R9270 STI lever represents a significant ergonomic improvement over the R9170 generation, with a refined hood shape designed to accommodate a wider range of hand sizes and grip positions without compromising lever reach or brake modulation control.
The included BR-R9270 caliper uses a 2-piston mono-body construction that Shimano designed specifically to reduce weight and improve rigidity compared to multi-piece caliper designs. Flat-mount only, it is compatible with 140mm and 160mm rotors using the appropriate adapter. The system communicates wirelessly with the rear derailleur for synchronized Di2 electronic shifting, and firmware is managed via the Shimano E-TUBE app. Purchasing the lever and caliper as a matched unit ensures correct hose length specification and eliminates compatibility questions between brake components. For road disc builds specifying the complete R9250 Dura-Ace Di2 groupset, this is the correct left-side brake and shift assembly.
