What Is It?
The Shimano CS-HG800-11 is an 11-speed road/gravel cassette with an 11–34T gear range. It uses Shimano's Hyperglide shifting technology to provide smooth, fast and reliable gear changes.

Best Suited For
Ideal for road cyclists, gravel riders, touring cyclists and endurance riders who want a wider 11-speed gear range without moving to a compact MTB-style cassette.
The 11–34T configuration is particularly useful for riders tackling steep climbs, hilly routes or long-distance rides where having a lower climbing gear can make a significant difference.
Important: The CS-HG800-11 is designed around Shimano's 11-speed Hyperglide system. Confirm your rear derailleur's maximum sprocket capacity and drivetrain compatibility before fitting a 34T cassette.
