After thorough testing, and becoming the choice of top-level pro racers, the RC-903s are road shoes designed to help you perform at your top level. This updated version builds off of the popular RC-902 with an improved retention system and heel cup, increased ventilation, and reduced weight. The SH-RC903 utilizes a pair of BOA Li2 dials that are adjustable in both directions, with an optimized cable routing for even, hotspot-free retention at the turn of a dial. The ultra-stiff carbon fiber composite sole rates 12/12 on Shimano's stiffness scale and is zone-optimized for peak power transfer, without sacrificing comfort as you power through your most competitive rides.
