Shimano has unveiled the SPD-SLR system, a comprehensive overhaul of its road pedal and cleat interface, marking the first significant update in over two decades. This integrated system aims to enhance cycling efficiency by reducing stack height, simplifying cleat adjustments, and improving overall stability.
Key Features of the SPD-SLR System:
-
Reduced Stack Height: The SPD-SLR pedals and cleats lower the foot’s position relative to the pedal axle, enhancing power transfer and stability. (bike.shimano.com)
-
Lighter Design: The redesigned cleats are up to 22% lighter than their predecessors, contributing to a more responsive feel. (bike.shimano.com)
-
Simplified Cleat Adjustment: Fore-aft adjustments are now made directly on the shoe, streamlining the setup process. (bike.shimano.com)
-
Easier Clip-In Mechanism: A wider catch zone and a narrower 10.5° engagement angle facilitate quicker and more secure clipping in. (bike.shimano.com)
Compatibility Considerations:
The SPD-SLR system is not backward compatible with the older SPD-SL pedals. While the new cleats physically fit SPD-SL pedals, Shimano advises against their use due to potential performance issues. (bike.shimano.com)
New Pedal Models:
-
Dura-Ace PD-R9300: Features a carbon composite body and a stainless steel plate for enhanced stiffness and durability. (bike.shimano.com)
-
Ultegra PD-R8200: Offers similar benefits at a more accessible price point. (bike.shimano.com)
S-Phyre SH-RC910 Shoes:
Designed to complement the SPD-SLR system, the S-Phyre SH-RC910 shoes feature a carbon ‘Hollow Core’ sole with a stiffness index of 12, ensuring efficient power transfer. The shoes also offer improved cleat position flexibility and a wider fit, accommodating various foot shapes. (bike.shimano.com)
