Of all that can annoy us on a bike, interrupted shifting makes the top of the list. So, it's a good thing that the Dura-Ace CS-R9200 12-Speed Cassette is here to let us push our limits without having to think about our next gear change. Be it climbs, sprints, or all-out descents, this cassette features everything we need to handle it all. Larger cogs maximize drivetrain efficiency, but also create compatibility with both Shimano 11- and 12-speed freehub bodies. And, that's all before we dive into Hyperglide+ features. Cassettes with this technology mean we no longer need to back off to shift. Instead, efficiency is maximized in every gear. Plus, this is all done without increasing weight.
