Shimano's GRX components are all tailor-made for gravel riding performance, and the RX750 wheelset is no exception. Like Shimano's other tried and true wheel offerings, the RX750 also uses an easily serviceable cup and cone bearing system within the steel hub body. The heavier steel at the hub is no penalty for rotational weight and helps extend the durability of the wheelset.

These wheels are specifically designed for gravel adventure riding. They are robust with stainless steel spokes, Center Lock compatible hubs on alloy rims. With an inner rim width of 21.6 mm, these wheels are designed for larger volume tires. The asymmetric rim profile of the GRX wheels increases durability and allows for even spoke tension, which results in improved riding stability and stiffness – for a sprightly and agile performance. In addition, they are are tubeless compatible.
