Take Note Please put a remark which Freehub System u need (Shimano HG 11sp/SRAM XDR 12sp/Campagnolo 12sp) Our HYPER range is the pinnacle of what's possible with wheel design. For 2020 we totally reengineered the wheel from the hub out. Carbon spokes give the best performance possible while ceramic bearings and an aero optimized rim make sure you're getting every bit of speed possible. No clever marketing gimmicks and just one simple, low price for the whole range.
