Gravel-ready RX880 wheelset delivers speed, strength, and simplicity
What Our Gearhead® Experts Are Saying:
"I mounted these up on my gravel rig for the Utah Mixed Epic, and they blew me away. They feel like road wheels on climbs and hold up like mountain wheels when the trail turns to rubble. Setup was a breeze tubeless, and they’ve stayed true after months of abuse."
We ride to escape, to connect with wild places, and to push past limits—so we need gear that does the same. The RX880 700c wheelset from Shimano is a prime example of that ethos. Shimano brings WorldTour-level tech to gravel with these lightweight, aerodynamic wheels built for the long haul. Whether we’re hammering over chunky washboard or carving up a fast fire road descent, the RX880 stays composed, responsive, and fast.
At just 1,395 grams for the set, these wheels feature a full carbon rim with a 32mm depth and a 25mm internal width—optimized for the wide gravel tires we love. Shimano’s DIRECT ENGAGEMENT freehub delivers rapid power transfer and reliability, while the refined lacing pattern improves torsional stiffness without adding weight. Whether we’re racing Unbound or logging big days on forgotten farm roads, the RX880 wheelset is built to ride hard and far.
