Shimano CS-HG800-11 11-Speed Cassette | 11-34T | HG Freehub
Shimano CS-HG800-11 11-Speed Cassette | 11-34T
Wide-range gearing for road, gravel, and adventure riding.
The Shimano CS-HG800-11 cassette delivers smooth, dependable 11-speed performance with an expanded gear range that makes climbing easier without sacrificing top-end speed. Originally developed alongside Shimano's Ultegra R8000 series, the HG800 has become a favorite among road cyclists, gravel riders, cyclocross racers, and bikepackers looking for additional low gearing.
With an 11-34T gear range, the CS-HG800 provides the versatility needed for everything from steep mountain climbs to fast group rides. Unlike many wide-range road cassettes, the HG800 is designed to fit standard Shimano HG freehub bodies commonly found on both road and mountain bike wheels, making it one of Shimano's most versatile cassette options.
Precision-machined sprockets provide fast, consistent shifting while the anodized finish enhances corrosion resistance and long-term durability. Whether you're building a gravel bike, upgrading your endurance road bike, or replacing a worn cassette, the CS-HG800 delivers the reliability Shimano is known for.
