Mechanical shifting, hydraulic braking, no batteries to charge. The ST-R8020 is the Ultegra lever for riders who want disc brake stopping power without going electronic, and Shimano ships it as a J-kit: lever, caliper and hose already connected and bled at the factory. Fit it, route the hose, ride. No bleed kit, no mineral oil, no guessing whether the air is out.

Left / front side, 2x11 mechanical, flat mount caliper, 1000 mm hose
This is the left lever and front caliper. On a standard road setup the left lever works the front brake and the front derailleur (2-speed). It suits Shimano 11-speed mechanical road drivetrains: Ultegra R8000, 105 R7000 or Dura-Ace R9100. The caliper is flat mount, and the 1000 mm hose is the correct front length for almost every frame size.
Please check before ordering: this is the left side only, sold individually, not a pair. It is mechanical, so it will not work with Di2, and it needs a flat mount frame, not post mount. Message us with your frame and groupset and we will confirm before you buy.
