What Does the Shimano Dura-Ace ST-R9270F-L Di2 Lever With Caliper Include?

The ST-R9270F-L is the left/front combination of Shimano's flagship Dura-Ace R9270 Di2 STI lever paired with its matching flat-mount hydraulic disc brake caliper for the front wheel. The lever handles wireless electronic front shifting through the Di2 system and integrates the hydraulic brake lever in a single ergonomic unit -- the defining architecture of the R9270 generation. Wireless Di2 means no lever-to-junction wiring, reducing cockpit cable complexity to just the hydraulic hose. The Dura-Ace-grade hydraulic caliper delivers the controlled, powerful stopping feel with the modulation and heat resistance that flat-mount road disc calipers at this tier are designed to provide.

Part of the Dura-Ace R9270 Di2 system. Flat-mount caliper. Requires Di2 battery (BT-DN300), E-Tube wiring, and compatible R9200/R9250 groupset components. Sold as left lever with front caliper only -- pair with ST-R9270F-R for the complete lever set. Hydraulic hose not pre-installed.
