The SHIMANO S-PHYRE SH-RC910 is SHIMANO’s flagship road racing shoe, engineered around one goal: maximum performance without compromising comfort.

Every element has been refined to create a more stable, efficient connection between rider and bike. A lower stack height, reduced weight and improved foot retention help maximise power transfer across thousands of pedal strokes, from sustained threshold efforts to the final sprint.

The carbon fibre heel cup with Anti-Twist Stabilisation provides exceptional foot hold, while the Carbon Hollow Core midsole delivers a rigid, efficient platform for pedalling. The new SPD-SLR platform also provides an expanded cleat adjustment range, making it easier to dial in your position.

Inside the shoe, SHIMANO DYNALAST 2.0 is designed to reduce foot fatigue during prolonged efforts, while the updated surround-wrapping upper creates a more precise, supportive fit around the foot. New ventilation perforations improve airflow to keep feet cooler during hard efforts.

SPD-SLR: Engineered as One System

SHIMANO designed SPD-SLR shoes, cleats and pedals as a complete system to create a more direct connection between rider and bike. The redesigned cleat-to-pedal interface reduces unnecessary movement while improving stability, efficiency and confidence.

A 2.3 mm lower stack height brings the foot closer to the pedal axle, enhancing stability, power transfer and control. A wider catch zone and narrower 10.5° engagement angle, compared with 15.5° for SPD-SL, provide faster, more natural engagement when accelerating, restarting or sprinting.

The redesigned SPD-SLR cleats are also up to 25% lighter than their SPD-SL equivalents, while high-contrast alignment markings make setup and cleat positioning easier and more repeatable.
