SHIMANO Introduces All-New SPD-SLR

Shimano has announced that its next-generation S-PHYRE road shoes, DURA-ACE and ULTEGRA pedals and updated cleats have been engineered together to deliver greater efficiency, stability and connection. Designed as one integrated platform, SPD-SLR creates a closer connection between rider and bicycle through a lower stack height, faster engagement, lighter components and simplified fit adjustments.

 

SHIMANO Introduces SPD-SLR: A New Integrated Road System That Brings Riders Closer to Every Pedal Stroke

Next-generation S-PHYRE road shoes, DURA-ACE and ULTEGRA pedals and updated cleats engineered together to deliver greater efficiency, stability and connection.

For decades, SHIMANO has believed that the best performance doesn’t come from individual components. It comes from the way every part works together.

That philosophy continues with the introduction of SPD-SLR, SHIMANO’s next-generation S-PHYRE footwear, DURA-ACE and ULTEGRA pedals and a new cleat system. Designed as one integrated platform, SPD-SLR creates a closer connection between rider and bicycle through a lower stack height, faster engagement, lighter components and simplified fit adjustments.

Rather than redesigning a single product, SHIMANO engineers refined every interface where power is transferred from shoe to cleat, cleat to pedal and rider to bike. To create a more efficient riding experience from the first pedal stroke to the final sprint.

 

Engineered as One System

Every watt begins at the rider’s foot. That’s why SHIMANO develops its road shoes, pedals and cleats together as a complete system. With SPD-SLR, every contact point has been re-engineered to reduce unnecessary movement while improving stability, efficiency and confidence. The result is a more direct connection between rider and bike, allowing power to flow more naturally while maintaining the comfort and reliability riders expect from SHIMANO.

Lower Stack Height

At the heart of SPD-SLR is a completely new cleat-to-pedal interface. By redesigning both the pedal platform and the cleat, SHIMANO has reduced stack height by 2.3 mm, bringing the rider’s foot closer to the pedal axle than ever before. That shorter distance creates a more stable pedalling platform, improves power transfer and enhances bike control whether climbing, sprinting or riding at threshold.

 

Faster Engagement

Connecting with the pedal should feel immediate. SPD-SLR introduces a wider catch zone together with a narrower 10.5° engagement angle, compared with 15.5° on SPD-SL, allowing riders to clip in more naturally and confidently while accelerating away from traffic lights, restarting after corners or launching into a sprint.

 

Lighter by Design

The redesigned SPD-SLR cleats weigh up to 22% less than their SPD-SL equivalents while maintaining the durability expected from SHIMANO’s race-proven road platform.

 

Easier Fit for Confidence

Small adjustments can make a significant difference over long rides. High-contrast alignment markings make cleat installation and repositioning faster and more intuitive, helping riders accurately reproduce their preferred setup while simplifying first-time installation.

 

DURA-ACE PD-R9300

Refined for Pure Racing Performance

SPD-SLR makes its debut on the new DURA-ACE PD-R9300, SHIMANO’s most advanced road racing pedal.

Designed for professional racers and performance-focused riders, the PD-R9300 delivers exceptional stability through an ultra-wide platform while maximising efficiency with its new ultra-low stack height.

An integrated stainless steel contact plate improves engagement and increases interface stiffness. While the axle design utilises wide bearings for a more even load distribution, providing a stiffness increase of 11% compared to the PD-R8200, enabling an even more direct power transfer under maximum load.

Internally, a heat-treated axle and refined bearing surfaces reduce rotational resistance by 53% compared to the PD-R8200, resulting in smoother rotation on every ride.

Key features include:

• Ultra-low stack height and no gap between the pedal and cleat improves stability and power transfer

• Injection-moulded carbon-composite body

• Extra-wide platform for maximum support

• Integrated stainless steel contact plate improves stiffness

• Reduced bearing resistance for smoother rotation

• New SPD-SLR interface for a seamless shoe-to-pedal connection

 

ULTEGRA PD-R8200

Race Performance for Every Ride

The ULTEGRA PD-R8200 brings the same SPD-SLR architecture to riders seeking race-inspired performance for training, competition and long days in the saddle.

Its lightweight carbon body with stainless steel contact plate delivers excellent stiffness, efficient power transfer and the same intuitive engagement characteristics as its DURA-ACE counterpart.

 

S-PHYRE SH-RC910

Engineered Without Compromise

The flagship S-PHYRE SH-RC910 has been sculpted for world-class racing performance.

Every contour has been refined to improve power transfer while maintaining exceptional comfort during the longest and most demanding races. At the highest level, performance is measured across thousands of pedal strokes rather than individual moments. The combination of lower stack height, improved foot stability, reduced weight and refined fit helps elite riders maintain efficient power delivery from the opening attack to the final sprint.

Key innovations include:

• Carbon Fiber Heel Cup with Anti-Twist Stabilisation for exceptional foot hold

• Carbon Hollow Core midsole engineered for maximum pedalling efficiency

• New SPD-SLR platform with expanded cleat adjustment range

• SHIMANO DYNALAST 2.0 to reduce foot fatigue during prolonged efforts

• Updated surround-wrapping upper for a more precise fit

• New ventilation perforations for improved breathability

 

SH-RC810

Race-Caliber Performance Inspired by S-PHYRE

The SH-RC810 brings flagship engineering to riders demanding uncompromising performance across training and racing alike.

Dual BOA® Li2 dials provide precise micro-adjustments, while SHIMANO DYNALAST 2.0, an external heel stabiliser and a rigid hollow-channel carbon midsole combine to deliver lasting comfort and efficient power transfer.

Additional features include:

• Dual BOA® Li2 Fit System

• New SPD-SLR platform with expanded cleat adjustment range

• SHIMANO DYNALAST 2.0

• External heel stabiliser for secure foot positioning

• Replaceable heel pads for longer product life

• Hollow-channel carbon midsole for ventilation and water drainage

 

One Platform, Four Cleats

SPD-SLR is available with four cleat options, allowing riders to choose the movement characteristics that best suit their biomechanics and riding style.

 

CL-SL100 (Red): A fixed-position cleat with zero float for riders seeking the most direct power transfer and a completely locked-in feel.

 

CL-SL120 (Blue): Provides one degree of float while maintaining a highly stable pedalling platform, making it ideal for riders, balancing efficiency with limited movement.

 

CL-SL130 (Gray): Designed to help riders transition to SPD-SLR pedals using most non-SHIMANO three-bolt road shoes.

 

Unlike the core SPD-SLR cleats, the CL-SL130 does not deliver the lower stack height or weight-saving benefits of the integrated SPD-SLR platform but offers increased adjustment range for fixed-mount outsoles.

 

Compatibility

SPD-SLR has been engineered as a complete ecosystem. While SPD-SLR cleats are compatible with existing SHIMANO SPD-SL road shoes, riders experience the full performance benefits when SPD-SLR shoes, cleats and pedals are used together.

The low-stack CL-SL100, CL-SL110 and CL-SL120 cleats provide simplified lateral positioning while fore-aft adjustment remains dependent on the shoe’s available adjustment range. Riders using previous SPD-SL SHIMANO shoes, including RC703 and RC503, retain the adjustment range available within each shoe.

For riders using fixed-mount outsoles, the CL-SL130 offers additional adjustment flexibility while remaining compatible with SPD-SLR pedals. SPD-SLR cleats are designed exclusively for SPD-SLR pedals and are not backward compatible with SPD-SL pedals.
