Supremely engineered for your fastest efforts. With its ultra sleek lines, optimal power transfer, and refined pro-grade features, the RC903 is the culmination of our most advanced technologies for a performance elevating race shoe that feels and functions unlike anything you’ve worn before.

- Premium Road Cycling Shoe: S-PHYRE RC903 is a high performance road racing shoe compatible with SPD-SL cleats
- Precise Fit: dual low-profile BOA® Li2 dials deliver quick and precise micro-adjustments
- Optimum Stiffness: reduces energy loss and maximizes power transfer
- Anti-twist Heel Cup: stabilizes heel to help manage the intense twisting forces caused by explosive acceleration
- Breathable Shoe: lightweight micro-fiber leather upper with perforated venting keeps feet cool during even your sweatiest pursuits
- Cleats sold separately


Anti-twist stabilizing structure within the heel cup offers unparalleled stability during explosive sprints. DYNALAST technology secures your foot in place, reducing power loss at the pedal and lessening fatigue during long rides, while the optimized toe-spring section reduces tension in your feet, calves, and hamstrings - so you can go further, faster.


How a shoe fits and feels defines its performance. The RC903 takes both to the next level with a 360º surround wrapping upper, a refined toe box fit, and a low-profile crossover lacing pattern with two BOA® Li2 dials for the most precise fit possible.
