GRX WH-RX870 Carbon Gravel Wheelset - Tubeless

5 out of 5 stars

Why We Like The Shimano GRX WH-RX870 Carbon Gravel Tubeless Wheelset

Built for all-terrain riding and racing, the Shimano GRX WH-RX870 Carbon Gravel Tubeless Wheelset offers quick acceleration on flat paths, steady climbs, and rolling hills alike. The lightweight carbon rim construction weighs in at just 1,461g for the pair, which is why we see this wheelset as a must-have for high-performance gravel riding. With a 25mm internal and 30mm external rim width, our wheels are suitable for tubeless-ready tires between 32 and 50mm, and when combined with Shimano's cup-and-cone ball bearing hubs, they deliver a quick response and exceptional stability during any ride.

Short term review

I've used it several times

Came with tubeless tape pre-installed and seating 34c Vittoria corsa pro controls was super easy with my Lezyne pressure overdrive cannister pump, then I put on an 11-30 dura-ace cassette, and 2 160mm dura-ace rotors, added sealant and with NO adjustments to my calipers or rear mech swapped them out onto my gravel bike and works perfect. I have done a couple hundred miles on them and they are awesome, fast, nice sound too, and look good.
