Shimano CS-R9200 Dura-Ace 12-Speed Cassette

Shimano cassette for the named series, 12-speed configuration — the rear cog stack that defines your gearing range. Shimano's HG / HG+ tooth profiles give the smooth, precise shifting that's the brand's reputation; matched pairing with the same-series chain and derailleur is what delivers the in-spec performance. Dura-Ace is Shimano's top-tier road groupset — the same parts the WorldTour peloton runs. Weight-optimised, finished to the tightest tolerances in the range. This is the Shimano CS-R9200 Dura-Ace 12-Speed Cassette.
