The Shimano RC810 road cycling shoe and Dura-Ace PD-R9100 pedal come together in one package built around a shared idea: less stack between the foot and the pedal axle. The RC810's low-stack carbon sole already shortens that distance on its own, and the PD-R9100 pedal cuts it further with a 14. 6-millimeter stack height and an extra-wide platform, so the two compound into one connected feel rather than each doing its own thing. Buying the pair together also 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 get asked constantly whether a given shoe and pedal actually work together, and this pairing skips that conversation entirely, the fit is already sorted before the box is even open."
