Standard OE replacement freehub body for the Zipp 188 hub. This hub was produced from 2009 to present.
The freehub comes with an alloy axle and seals. They are super light, precision ground to tight tolerances and easy to swap from wheel to wheel. The three large pawls mounted on a spring-clip design are perfect for solid action and durability. The freehubs are color coded and easy to identify: blue for Campagnolo and red for Shimano.
