One used 11-29 tooth Campagnolo Super Record 12 Speed Sprocket Cassette. Light use on flat Florida roads. It was on my second set of wheels and didn’t get ridden much. Same gears/cassette photographed on black and white, because you can see the gears better on the different backgrounds. PLEASE READ—-ONLY FOR SALE IN LOWER 48 UNITED STATES. Campagnolo Super Record Cassette. The Super Record 12-Speed cassette features thinner sprockets, tighter tolerances, and space-saving dimensions that are the same as those of the 11-Speed versions. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing users to find the perfect ratio for any situation. In addition, the closer sprockets ensure faster, quieter, and more precise shifting thanks to the special tooth design and surface treatment which guarantees a longer life span. The six larger cogs are available in two single-piece steel triplets, to avoid energy loss. Matching-thickness spacers eliminating the possibility of error during installation. Same overall dimensions as the 11 Speed; there are no wheels to change or update. Drive Type: Campagnolo 10/11/12.
