Shimano 105 ST-R7120 Right Shift/Brake Lever with BR-R7170 Rear Brake – Precise Shifting and Reliable Braking

Shimano 105 ST-R7120 with BR-R7170 – a road bike mechanical shifting and hydraulic braking set designed for cyclists who value precise control, reliability and the traditional feel of mechanical shifting. Part of the Shimano 105 R7100 component group, this set combines an ergonomic right-hand shift and brake lever with an efficient rear disc brake. It is a practical solution for both upgrading an existing road bike and building a new one where smooth operation, easy maintenance and confident control in a variety of riding conditions are important.

Key features:

• Mechanical 12-speed shifting: the ST-R7120 lever is designed for the Shimano 105 R7100 mechanical 2x12-speed drivetrain, providing precise and reliable control of the rear derailleur.
• Dual Control (STI) technology: integrated shifting and braking functions in a single lever allow convenient bike control without changing hand position.
• Updated shifting mechanism: the improved internal construction provides light and smooth shifting. Up to two rear gears can be shifted with a single lever movement.
• Ergonomic lever construction: the updated lever shape and brake lever position make the controls easier to reach for different hand sizes and reduce the effort required for braking.
• Reach Adjust: the brake lever reach can be adjusted with a tool to suit individual hand size and preferred grip position.
• Shimano 105 BR-R7170 rear hydraulic caliper: provides effective braking and precise modulation in a variety of weather and road conditions.
• Increased brake pad clearance: approximately 10% more clearance between the pads and rotor makes brake adjustment easier and helps reduce the likelihood of unwanted rubbing and noise.
• L05A-RF brake pads: organic (Resin) pads with cooling fins help dissipate heat more efficiently and provide consistent braking under higher loads.
• Flat Mount: the compact rear brake construction is designed for modern road bike frames using the Flat Mount brake mounting standard.
• Shimano mineral oil: the hydraulic braking system uses dedicated Shimano mineral oil to provide smooth and reliable brake operation.
• Pre-assembled hydraulic system: the brake caliper is supplied with a pre-connected brake hose filled with mineral oil, helping simplify installation.
• Easy maintenance: mechanical shifting requires no batteries or electronic components, while the hydraulic brake construction is designed for convenient bleeding and adjustment.
• Compatibility: Shimano 105 R7100 mechanical 2x12-speed drivetrain.
