The Shimano 105 ST-R7025-L is a left-hand hydraulic disc brake and mechanical shift dual control lever purpose-built for riders with smaller hands. Part of the R7000 series 105 groupset, it delivers the confident, modulated stopping power of hydraulic disc braking alongside precise 11-speed road shifting — all from a compact reach lever blade that puts the brake within comfortable reach without rotating your grip forward.

Highlights

• Short reach geometry: Lever blade starts 4mm closer than the standard ST-R7020, letting riders with smaller hands brake securely with a natural grip.
• Hydraulic disc braking: Shimano mineral oil hydraulic system provides consistent, powerful braking in all weather conditions with excellent modulation and feel.
• 11-speed mechanical shifting: Controls the front derailleur with the same quick, reliable action road cyclists expect from Shimano 105.
• Adjustable reach: Tool-included reach adjuster allows up to 15mm of lever reach customisation to suit different hand sizes and riding preferences.
• Ergonomic lever shape: Slimmer, contoured lever body matches the design language of Ultegra R8020 for a secure, comfortable grip in the drops and on the hoods.
• Funnel bleeding port: Integrated funnel bleeding system simplifies maintenance for mechanics and home wrenchers alike.
• OptiSlick inner cable: Included OptiSlick-coated shift cable and OT-SP41 outer casing deliver smooth, precise front derailleur actuation.

Small Hands, Full Control

The ST-R7025-L was developed specifically to address the challenge of hydraulic lever reach for riders with smaller hands. Where a standard lever requires stretching or repositioning the grip to access the brake, the short reach geometry of the R7025 keeps the lever blade within natural reach. The result is confident braking without compromising your hold on the handlebar — important for descending, cornering, and riding in wet conditions.

Shimano 105 R7000 Quality

The 105 R7000 groupset represents Shimano's benchmark for performance road cycling, bringing trickle-down technology from Dura-Ace and Ultegra into a reliable, accessible package. The ST-R7025-L shares the ergonomic refinements and lever feel of its higher-tier siblings, including an increased reach adjustment range and a lever profile optimised for the drops. Mineral oil hydraulic fluid is non-corrosive and easy to work with during maintenance.
