    ZIPP 303 S WHEELSET Review

    Posted by Cyclocrossmagazine on 21st May 2020

    The key innovation is in the 303 S’s rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tire bed is a full 7mm wider, at 23mm internal width.

    The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide.
