Cassette Buying Guide

Road riders will find Shimano's HYPERGLIDE+ 12-speed cassettes (Dura-Ace CS-R9200, Ultegra CS-R8100) alongside proven 11-speed options; mountain and gravel riders can choose wide-range Micro Spline 10-51T cassettes or SRAM Eagle 10-52T for XD drivers. A fresh cassette shifts best with a matching chain — and if you're upgrading the whole drivetrain, browse rear derailleurs or the full Shimano and SRAM ranges.

Quick guide: match the cassette to your drivetrain speed (11-speed with 11-speed, 12-speed with 12-speed) and check your freehub — Shimano 12-speed road fits the standard HG road freehub, Shimano 12-speed MTB needs Micro Spline, and SRAM Eagle 10-52T needs an XD driver.

Cassette FAQs

Will a Shimano 12-speed road cassette fit my 11-speed wheels?

Yes — Dura-Ace CS-R9200 and Ultegra CS-R8100 12-speed road cassettes mount on the same standard HG road freehub used by 11-speed wheels.

Do I need a new chain when I replace my cassette?

We recommend it — a worn chain wears a new cassette quickly. Always match the chain speed to the cassette (e.g. a 12-speed chain for a 12-speed cassette).

Are these cassettes genuine?

Yes — every cassette we sell is brand new and unopened in original Shimano or SRAM retail packaging.
