The Shimano S-PHYRE RC910 road cycling shoe and Dura-Ace PD-R9100 pedal come together in one package, pairing Shimano's lowest-stack road shoe with its longest-standing top-tier pedal platform. The RC910's carbon hollow core sole already sits closer to the pedal axle than any Shimano road shoe before it, and the PD-R9100 adds its own 14. 6-millimeter stack height and extra-wide contact surface on top of that. Buying the pair together settles the cleat compatibility question up front instead of leaving a rider to match parts on their own. What Our Gearhead(R) Experts Are Saying:"I've built up a lot of race bikes with this exact shoe and this exact pedal separately, and having them boxed together saves a rider the back-and-forth of confirming the cleat pattern lines up before the parts even arrive."
