Shimano CUES ST-U4030 Shifters Hydraulic Confidence, Drop Bar Simplicity Riders building up a road or gravel bike who want genuine hydraulic disc brake performance without jumping to a higher price tier have a great option here. The ST-U4030 is a hydraulic Dual Control Lever that puts braking and shifting in the same hand position, the way it should be on a drop bar setup. The lever position and bracket shape were developed through research on a wide range of hand sizes, so the reach feels natural whether your hands are large or small. Shift internals draw from MTB technology, which means the action is smooth enough for one-finger operation front and rear. It's the kind of component that gets out of your way and lets you focus on the ride.
