Classified uses a proprietary cassette for increased durability and lighter weight. We offer several options so you can optimise your drive train to suit your riding style.
Classified cassettes are compatible with Shimano or SRAM 11 or 12 speed rear derailleurs, and Campagnolo 11 and 13 speed rear derailleurs, preferably with a clutch. Make sure the maximum sprocket capacity of your rear derailleur fits the chosen Classified cassette. By making use of a separate shift button, both mechanical and electronic rear derailleurs are compatible with a Classified cassette.
You can find an overview of the actual cassette compatibility chart here.
