While most premium cycling shoe designs are split between a single or dual BOA retention system, Shimano has decided on a mix of old and new for its latest RC9 PWR road shoe, opting for a single BOA Li2 dial and a velcro toe strap system.
Borrowing heavily from its top-tier S-Phrye RC9 brethren, the RC9 PWR features the same upper and full-carbon sole, but relies on the aforementioned closure set-up.
Why the design choice?
According to Shimano the RC9 PWR is aimed at time trialists, powerful sprinters and track cyclists who are looking for a more secure fit during all-out efforts.
Offered in white only, the RC9 PWR is available in a wide-range of sizes.
