The SRAM GX Eagle Power Meter D1 Crankset is built for riders who want tough trail performance with clean, reliable power data baked right in. Its DUB-PWR design hides Quarq power measurement inside the crank spindle, using left-side data to estimate total watts without adding bulk or complicating your setup. Composite bashguards help protect the chainring from rock strikes and scrapes, and each guard can be removed on its own for easy service or replacement.
