The Super Record cassette is similar to the Record cassette except it offers an unprecedented 6 Titanium cogs - this is not a misprint or typo. That means there are more Ti cogs on this cassette than steel. The 5 remaining steel cogs have been nickel plated for added durability. All 11 cogs are fitted onto an alloy carrier for even force distribution on the freehub body. The cogs have also been machined to the new Ultra Shift® tooth profiling for much improved shifting and chain glide. Lightweight alloy lockring included.
