Shimano&';s ultimate road competition shoe gets a Dura-Ace facelift. The limited-edition Dura-Ace style will feature familiar specs to anyone acquainted with the original RC902. Anti-twist stabilization in the heel cup secures optimal foot position for acceleration and high-tempo cadences. While Shimano&';s 360 degrees surround wrapping upper is shared with every S-Phyre shoe, the unique black enameled finish is exclusive to this S-Phyre Special Edition shoe. Integrated seamless midsole and upper construction set a new level of fit, stability, and lightweight performance. Also exclusive is the low-profile BOAA(R) Li2 metal dial closures allow for quick micro-adjustments and a custom-feel fit. Once this sells out, it&';s gone!
