Campagnolo Record 11 Speed Cassette 12 25t. Quite simply, the Campagnolo Record 11 speed cassette is a functional work of art. Featuring the legendary Italian manufacturer's exquisite Ultra Shift technology, shifting the chain through the gears is an utter pleasure: whisper quiet, lightning fast and super precise even when under plenty of load. Technologically it's identical to Campy's flagship Super Record cassette, the only difference being the Record version has a mix of eight steel cogs and three titanium to the Super Record's five steel cogs and six titanium. While the Record cassette is ever so slightly heavier, what you also gain is an extended lifespan with more steel cogs.
