The S-Phyre SH-RC903 is Shimano's WorldTour-proven race shoe. Right now it's $349.99 at Bikebug, down from $439.99. If you've been waiting for the right time to step up to a pro-level road shoe, this is it.
Why choose the RC903
- Full carbon sole: rated 12 on Shimano's stiffness scale, for direct, efficient power transfer.
- Dual BOA Li2 dials: fine-tune the fit in both directions, even mid-ride.
- DYNALAST shape: toe spring designed to reduce energy loss through the pedal stroke.
- Wraparound upper: holds the foot securely and evenly, without pressure points.
What pedals best suit the SH-RC903?
The RC903 uses the standard 3-bolt cleat mount. It pairs with Shimano SPD-SL pedals such as Dura-Ace PD-R9100, Ultegra PD-R8000 and 105 PD-R7000, and with other 3-bolt road systems like Look Kéo.
Planning to upgrade to Shimano's new SPD-SLR pedals (Dura-Ace PD-R9300 or Ultegra PD-R8200)? You'll need the new grey SPD-SLR cleat, which is made for standard 3-bolt shoes like the RC903. Your current SPD-SL cleats won't fit the new pedals. For the full breakdown, read our guide Shimano SPD-SLR Cleats & Pedals Explained, or shop pedals & cleats.
FAQ
What's the difference between E-Width (wide) and standard fit?
The E-fit RC903 is built on Shimano's wide last, which gives a roomier forefoot and toe box for broad or high-volume feet. The heel is the same as the standard RC903, so it stays locked in.
Are the BOA dials replaceable?
Yes. BOA dials can be replaced if damaged, so a crash won't end the life of your shoes.
