This listing is the \u003cstrong\u003eShimano HG driver body version\u003c\/strong\u003e. If you run a SRAM XDR cassette, you need the XDR version of this wheel instead.\u003c\/p\u003e\n\u003cp\u003eThe rim is where the performance comes from. A \u003cstrong\u003e25mm internal width\u003c\/strong\u003e lets a 30mm-plus tire hold its designed shape at low pressure, producing a larger contact patch, better grip on wet or loose surfaces, and less rolling resistance than a narrow rim at high pressure. The symmetrical 40mm profile keeps crosswind behavior predictable rather than twitchy, and the \u003cstrong\u003e286lb \/ 130kg maximum system weight\u003c\/strong\u003e is generous for a carbon road wheel — higher than several more expensive wheels in Zipp's own range.
