Engineered to lead the WorldTour peloton, the PD-R9300 pedal debuts the refined SPD-SLR interface. Shimano has drastically reduced the stack height by 2.3mm, pulling your foot closer to the axle to eliminate power loss and enhance cornering clearance during high-speed efforts.
The lightweight injection-moulded carbon-composite body features an extra-wide platform lined with an integrated stainless steel contact plate. This design minimises flex under heavy loads, ensuring every watt of effort drives you forward when launching into a sprint or ascending steep climbs.
Internally, heat-treated axles and refined bearing surfaces reduce rotational resistance by a massive 53% compared to previous generations. Combined with a wider clip-in catch zone, the PD-R9300 delivers smooth spinning and effortless, intuitive cleat engagement.
SPD-SLR System: Ultra-low stack height reduces distance to the axle for maximum cornering clearance and power transfer.
Carbon Composite Body: Premium injection-moulded carbon construction delivers incredible stiffness without extra bulk.
Ultra-Low Drag Bearings: Heat-treated axle assembly reduces rotational friction by 53% for silky-smooth pedalling.
Weight: 228g per pair (standard axle)
Body Material: Injection-moulded carbon-composite with stainless steel plate
Engagement Angle: 10.5° narrow angle for faster clip-in
✅ Competitive Racers: Designed for maximum power transfer and zero movement slop during out-of-the-saddle sprints.
✅ Gram-Conscious Builders: Ultra-lightweight carbon design keeps overall bike weight as low as possible.
✅ High-Cadence Cyclists: Reduced bearing friction keeps every pedal stroke effortlessly smooth over long distances.
❌ Budget-Conscious Riders: Premier flagship pricing makes lower-tier Ultegra or 105 pedals a better value choice.
❌ Commuters & Casual Cyclists: Single-sided road engagement requires dedicated road shoes with rigid three-bolt cleat patterns.
❌ Gravel & Dirt Enthusiasts: Open road design easily clogs with mud, making off-road SPD pedals better suited for dirt.
Pair these pedals with Shimano S-PHYRE road shoes to take full advantage of the ultra-low SPD-SLR stack height. When installing new cleats, use the high-contrast alignment markings to mirror your preferred cleat angle perfectly, and apply a small dab of grease to the axle threads before torquing to ensure silent operation and easy future removal.
