It weighs \u003cstrong\u003e1180g\u003c\/strong\u003e (not counting tubeless tape and some metal parts). Black Inc made the ZERO 3.0 lighter than earlier versions by switching to \u003cstrong\u003eTextreme carbon fiber\u003c\/strong\u003e while keeping the same hub. The goal is a disc that saves weight without losing strength.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEach wheel is \u003cstrong\u003ehandmade, with up to 180 hours of work per disc\u003c\/strong\u003e from layup through quality control.

For a rear disc, saving weight without losing stiffness matters because the wheel carries drivetrain load on every pedal stroke.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eA 21mm internal \/ 30mm external rim\u003c\/strong\u003e is sized for 25mm tires.
