Daily recreational riding on very hilly secondary and tertiary roads, using 700x25 tubeless tires. With around 1,000 miles on the wheels, I am totally pleased by the build and performance. I didn't like the "modern" DT Swiss version of the quick-release, but they proved to be just fine. Schwalbe tubeless tires were easily installed with soapy water and a basic floor pump. Removable valve cores made it a cinch to install sealant with an injector. It's DT, so of course the rear hub sounds perfect. I don't anticipate and problems with this product.
