A better way to produce aluminium Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint. Shimano CUES Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano's new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings. Shimano LINKGLIDE LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting - along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
