The Rocket 2 11-52t 12 speed cassette features 7 steel cogs on an alloy carrier and 5 alloy cogs cut from a single forged billet of AL7075-T6. This produces a lighter and stronger cassette where parts can be replaced if they become damaged without having to throw away the entire cassette. The cogs are forged and ramped for precise shifting, and spacing is tightly controlled between the cogs. The cogs are then surface treated with a hard coating to resist wear. The cassette is designed to fit on a standard freehub body for an easy upgrade without having to change wheelsets.
o 11-50t & 11-52t cassettes feature tooth ratios for optimal gear selection.
