The WH-M9220 has been developed with a focus on the Enduro World Series races and service friendliness, making it Shimano's strongest full carbon wheel to date. Featuring a hookless 30-millimeter carbon rim, brand new XTR hubs, and traditional 28h stainless steel J-bend spokes, the WH-M9220 is built for durability and is easy to repair if something goes wrong.
