New Super Record 12 Speed sprocket cassettes: innovation which gives the user great advantages, thanks to the matching dimensions and complete compatibility with wheels and frames. The rider has always been Campagnolo’s focus, and the goal has always been facilitating their performance; making the impossible possible. Adding an additional sprocket might seem simple, however, we have not only succeeded in maintaining the same footprint, but also improving the component’s performance and durability, which was a tricky challenge! The new Super Record 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets, meeting everyone’s needs with just two (11:29; 11:32) cassettes. The addition of the twelfth sprocket allows a linear upshift or downshift by a single tooth, up to the seventh gear, allowing the cyclist 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 lifespan. The 6 larger sprockets are also available in two single-piece steel triplets, to avoid energy loss. Mounting the cassettes is easy thanks to matching-thickness spacers.

The Campagnolo EKAR GT 13-speed cassette is available in different options that complete the range and reflect the different specializations on the gravel scene to deliver very smooth gear ratio progression.

Construction of the EKAR GT cassette retains the Campagnolo design philosophy with a single block for the larger sprockets, five individual sprockets with spacers in premium 7075 aluminum to give the cassette optimum lightness and reactivity. - Features a compact design with fast, light shifting, and greater chain security - Resistant design and materials provide durability you can count on - Small jumps for the initial sprockets offers riders with an optimum cadence - Bigger jumps for the larger sprockets allow you to adapt to any kind of ride - Cassette in aluminum and steel to combine resistance and lightness - For use with Campagnolo N3W freewheel bodies only
