ZRACE ALPHA EX 11-Speed HG Cassette Construction and Performance
The fully hollow CNC construction removes material from non-critical zones while maintaining structural integrity for reliable shifting under load. Precision engineering creates super light weight without sacrificing the rigidity needed for consistent chain engagement across all sprockets. Each tooth profile matches OEM specifications, ensuring compatibility with existing Shimano and SRAM derailleurs on your current drivetrain setup. The HG spline design works with all modern road bike freewheels and bottom brackets, making installation straightforward on any platform. Hard-anodized aluminum resists corrosion and abrasion, protecting your investment through seasons of demanding road racing.
