Overview
Why Is the Shimano CS-HG50 the Right 9-Speed Cassette for Sora Road Builds?
The Shimano CS-HG50-9 is a 9-speed road cassette built on Shimano's proven HYPERGLIDE shifting platform, delivering fast, responsive indexed shifting with specially positioned shift ramps and optimized tooth profiles for reliable chain control during gear changes. Designed for 9-speed road drivetrains, the 12-25T range is a classic close-ratio road specification that keeps gear steps tight across a flat to rolling terrain range for efficient cadence management at higher speeds.
Compatible with all Shimano 9-speed road drivetrains including Sora R3000. Requires a standard Shimano 9-speed freehub body and a 9-speed chain.

FAQ
Good questions
Get to know Shimano

There's more to Shimano than this one product. Our Shimano page has the full Shimano lineup we carry and more about the brand.
Visit the Shimano page →Is the 12-25T range appropriate for hilly terrain?
The 12-25T is a close-ratio, flat-terrain specification. For riders who tackle regular climbing, a wider ratio cassette such as 11-28T or 11-32T would provide more useful low gearing.
Is the CS-HG50-9 compatible with Shimano Tiagra and other 9-speed drivetrains?
Yes. The CS-HG50-9 is compatible with all Shimano 9-speed road drivetrains including Sora R3000 and equivalent groupsets.
What chain is required?
Use a Shimano 9-speed chain such as the CN-HG53 for correct fitment and shifting performance with this cassette.
