What Makes the Shimano Ultegra CS-HG800 the Versatile 11-Speed Cassette?

The Shimano Ultegra CS-HG800 is an 11-speed cassette engineered for compatibility across both road and MTB 11-speed drivetrains, bringing Hyperglide shift ramp precision to riders who push into mixed terrain. The 11-34t range makes it a popular choice for endurance road cyclists, gravel riders, and adventure bike builds where a standard 11-28t or 11-32t runs short on climbing range -- the extra 2 teeth on the large cog makes a real difference on sustained grades without switching to a dedicated MTB cassette. Reliable Ultegra-tier construction ensures long service life even under varied conditions.

Compatible with Shimano 11-speed road and MTB drivetrains including Ultegra R8000, 105 R7000, and Deore XT M8000. Fits standard HG freehub bodies found on both road and MTB wheels. Requires a Shimano 11-speed chain. A versatile, high-quality cassette for riders who range beyond typical road terrain.

FAQ

Does the CS-HG800 work with Shimano road derailleurs?

Yes. The CS-HG800 is compatible with Shimano 11-speed road rear derailleurs including Ultegra R8000 and 105 R7000. Note that road rear derailleurs may not accommodate the full 34t range depending on their maximum sprocket capacity -- check derailleur specs before combining.

What is the difference between the CS-HG800 and CS-R8000?

The CS-R8000 is the road-specific Ultegra cassette optimized for road drivetrains and comes in closer-ratio configurations (11-25t through 11-34t). The CS-HG800 offers cross-compatibility with MTB 11-speed drivetrains and is particularly suited to riders who want wider range on a road or adventure bike.

What freehub does the CS-HG800 require?

The CS-HG800 uses the standard Shimano HG freehub body, which is the most common freehub on both road and MTB wheels.

Best For

Endurance road cyclists, gravel riders, and adventure cyclists on Shimano 11-speed drivetrains who want wider climbing range than a standard close-ratio road cassette provides.
