CS-R8101 ULTEGRA 12 SPEED CASSETTE

The Shimano CS-R8101 Ultegra 12-Speed Cassette is engineered for riders who demand smooth, consistent performance across the varied terrain and climate that define cycling in India. Designed as part of Shimano’s race-proven Ultegra ecosystem, the cassette delivers crisp shifting with a refined tooth profile that balances power transfer, cadence stability, and high-speed efficiency. Whether used for fast group rides, long-distance training blocks, or triathlon gear setups in India, the 12-speed configuration ensures a wider range without gaps that interrupt rhythm on rolling terrain. Heat-tolerant materials help maintain performance during long summer efforts, while its lightweight build supports climbing efficiency without sacrificing durability. The cassette integrates seamlessly with Shimano’s latest Di2 and mechanical drivetrains, offering reliable performance even under load. Built for riders who want precise control and consistent handling during everyday training and weekend races, it brings pro-level refinement to real-world Indian riding conditions. Available now in India at Cobbled Climbs.
