The Shimano Sora ST-R3000-R is the right-side dual control lever for 9-speed road bike drivetrains, combining shifting and braking in a drop bar STI design. It suits road cyclists upgrading or building bikes with Shimano 9-speed components, including Sora rear derailleurs and Shimano/SRAM 9-speed cassettes. This lever works with short pull Super SLR brake calipers common on road setups.

Key features include adjustable reach for different hand sizes: use a 2mm hex key under the hood to move the brake lever closer to the bar, aiding riders with smaller hands or those spending time in the drops. Internal cable routing keeps handlebars tidy and reduces steering friction. It shifts up to three cogs at once for quicker gear changes during rides. The build uses an aluminum main lever with a graphite-reinforced plastic bracket body. Installation requires standard road brake cable housing and derailleur cables; readjust brakes after reach changes as it tensions the cable.
