Shimano S-Phyre SH-RC903 – Pro-Level Road Racing Shoes
The S-Phyre SH-RC903 is Shimano’s WorldTour-proven race shoe, built for riders who want every watt to reach the pedals. This black colourway gives a sleek, understated look that stays clean-looking through winter kilometres and wet-weather training.
