SHIMANO 105 CS-R7101 12-SPEED ROAD CASSETTE
HYPERGLIDE+ TECHNOLOGY — 11-34T WIDE RANGE — OEM BULK
Experience seamless, high-performance 12-speed road shifting with the genuine Shimano 105 CS-R7101-12 / CS-R7100 12-Speed Cassette. Featuring Shimano's proven HYPERGLIDE+ technology and a versatile 11-34T wide gear range, this cassette delivers ultra-smooth gear changes under heavy pedaling loads, making steep climbs easier and flat high-speed efforts more efficient. This OEM Bulk version offers professional-grade quality at an exceptional value.
FEATURES
- Advanced HYPERGLIDE+ Shifting: Precision-engineered tooth profiles and shift ramps allow continuous, crisp gear changes up and down the cassette without lifting off the pedals, ensuring uninterrupted power transfer during sprints and climbs.
- 11-34T Wide Climbing Range: The 34T low gear provides a generous 1:1 gear ratio when paired with a standard 34T inner chainring, allowing you to conquer steep mountain passes while maintaining a smooth pedaling cadence. Gear combination: 11-12-13-14-15-17-19-21-24-27-30-34T.
- Broad Freehub Compatibility: Unlike 12-speed mountain bike cassettes, this road 12-speed cassette mounts onto existing standard 11-speed Shimano/SRAM road HG freehub bodies—making upgrading your wheelset easy and affordable.
- Premium Construction: Features nickel-plated steel cogs for durability and corrosion resistance, mounted on a lightweight anodized aluminum spider and lockring.

- Chain Compatibility: Requires a Shimano 12-speed HG road/MTB chain (e.g., CN-M6100, CN-M7100, CN-M8100, CN-M9100).
