Bring wireless gravel performance to your cockpit with the Shimano GRX ST-RX715-R — the right-hand Di2 dual control lever from the GRX RX717 series. It combines cable-free 12-speed electronic shifting with a powerful, mineralóil hydraulic disc brake in a single, gravel-tuned package, giving you clean lines, confident braking, and crisp gear changes on any surface.

Highlights

• Wireless 12-speed Di2 shifting: no shift cables means a tidier, lower-maintenance cockpit with consistent gear changes every time.
• Servo Wave braking: quick initial lever engagement followed by strong, progressive modulation for confident control on gravel and paved surfaces.
• Long battery life: two CR1632 coin cells deliver up to four years of worry-free riding, and replacement is quick and simple.
• 16.4mm reach adjust: dial the lever closer or further to suit your hand size and riding position.
• Free stroke adjustment: set the bite point precisely where you want it for your preferred braking feel.
• E-TUBE app compatible: reassign the two shift switches to custom functions via the Shimano E-TUBE Project app.
• Broad Di2 compatibility: cross-compatible with all Shimano 12-speed wireless Di2 systems — GRX, Dura-Ace, Ultegra, 105, XTR, and Deore XT.

Wireless electronic shifting

The ST-RX715-R is the right-hand lever in Shimano's GRX RX717 Di2 groupset and controls the rear derailleur over a fully wireless connection. Two conveniently positioned shift switches are within easy reach from both the hoods and the drops, and you can remap their functions in the E-TUBE Project app to match your preferred shifting style.

Hydraulic disc braking with Servo Wave

The integrated hydraulic brake circuit uses Shimano mineral oil (SM-DBOIL) and Servo Wave technology to deliver a fast initial bite and smooth, powerful modulation. The gravel-specific hood profile is ergonomically shaped for a secure, fatigue-free grip across long days on varied terrain — whether you are riding from the hoods or the drops.

Dial in your fit

Reach Adjust lets you move the lever blade in 16.4mm of travel to find your ideal hand position, while Free Stroke adjustment fine-tunes where braking force begins, so the lever responds exactly how you expect it to.

Compatibility & fit

The ST-RX715-R is a right-hand lever only (Shimano does not produce a left-side ST-RX715). It is designed for drop handlebars and is part of the 12-speed GRX RX717 wireless Di2 system. It is cross-compatible with all Shimano 12-speed wireless Di2 rear derailleurs. Pair it with a left-side BL-RS717 brake lever for a clean 1×12 gravel cockpit. Hydraulic hoses SM-BH90-J-SSR and SM-BH90-JK-SSR are compatible. Following Australian convention, the right lever controls the front brake. Please confirm your derailleur, caliper, and full Di2 system compatibility before purchasing — contact us if you need help with fitment.
