Losing or damaging a skewer shouldn't send you hunting for a mismatched replacement, and Shimano's Dura-Ace WH-R9100 quick release is the direct-fit answer for anyone running an R9100 wheelset. There are two SKUs here: the Y0B198010 front at 133mm and the Y07E98010 rear at 163mm. Both use the internal cam mechanism that has anchored Dura-Ace skewers for decades, and both are the same parts Shimano specs on the R9100 wheels from the factory. If you're coming off a lighter third-party skewer that never felt quite planted, this is the fix.

The internal cam is the whole story. exposed on the dropout face, which keeps the working surfaces cleaner and better lubricated over time. In practice that translates to consistent clamping force across dropouts of varying thickness, so you get the same secure bite whether you're clamping into a thin alloy fork end or a chunkier carbon dropout. The tradeoff is honest: these aren't the lightest skewers out there, but the stiffness and lever feel are on a different level than featherweight titanium alternatives.

Front and rear are sold separately, so confirm which one you need before ordering. The 163mm rear covers standard 130mm road hub spacing on the R9100-series wheels. The lever action carries over the aerodynamic profile introduced with Dura-Ace 9000, tucking close to the fork leg and chainstay, but the R9100 gets the polished black fade finish that sets it apart from the silver 9000-series skewers that came before....
