Williams EVORA 10 Speed Cassette

The Williams EVORA cassette offers fast, smooth shifting with all Shimano and SRAM 10 speed drive trains. Sprockets are mounted using two alloy carriers to keep the cassette light and reduce wear on freehub bodies. Cold rolled steel cogs are progressively tooled to keep tolerances incredibly tight. Then cogs are heat treated using an Ionized Chemical Exchange Vacuum Furnace to achieve a carbonizing level that far surpasses other cassettes on the market. Those are big words, but when you break it down you get a lightweight cassette that offers smooth shifting and unmatched durability.
