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. Small jumps for the first 6 sprockets, which increase in the second half with the larger sprockets, ensures an optimum experience on the saddle and helps you get the best from your performance on difficult routes and terrain. 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

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 Super Record Wireless cassettes were conceived, studied, and designed to guarantee cyclists with the smoothest shifting across the entire range of combinations. For this reason, closer jumps are key to the pedaling experience of all cyclists, who are always guaranteed perfect cadence in any situation. These cassettes embody excellence in the search for performance, lightness, and durability. Smooth shifting is guaranteed by single-tooth jumps up to the seventh gear, especially in the second half of the cassette where jumps are a maximum of three teeth between one gear and the next. Devised and designed from scratch, the Super Record Wireless cassettes mount the N3W freewheel body present on all new-gen Campagnolo road wheels. The N3W is very versatile, with the same groove profiles as the classic Campagnolo freewheel body, but lighter and 4.4 mm shorter. - Provides perfect cadence with gear combinations that enable fast up- and down-shifting, with an extremely smooth fluid gear inch ratio, to guarantee constant cadence in any situation - Thanks to the use of special steel and processes with minimum tolerances, these cassettes have been designed to be durable and resistant - Designed to be installed on the N3W freewheel body, present on all Campagnolo new-gen road wheels - Same-thickness spacers are easy to install without any risk of error - Compatible with Campagnolo 12-Speed C-Link and Ultra-Link chains
