The 1x system is ideal for gravel with the 13-speed configuration that lets you work on a complete range of transmission gear ratios thanks to a 9-tooth sprocket.

The Ekar GT 13-speed cassette is available in four different options, from 9/36 to 10/48, which complete the range and reflect the different specializations on the gravel scene and each combination delivers very smooth gear ratio progression. Small jumps for the first 6 sprockets, which increase in the second half with the larger sprockets. This characteristic ensures an optimum experience on the saddle and helps you get the best from your performance on difficult routes and terrain.

The wide selection of larger sprockets gives a more compact cassette for endurance events and longer gears for more adventurous riders. The cassette combinations are partnered with easy-to-replace dedicated chainrings to offer the widest range of gear ratios, smooth changing and maximum efficiency and, unlike the 2x systems, no waste. Two of the four combinations have a 9-tooth sprocket. In-depth comparative tests have shown that the 9-tooth sprocket is as efficient as any 10- or 11-tooth sprocket, without any additional friction thanks to its special profile tooth design, so that none of the power produced is lost.

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 aluminum 7075 and an initial triple or quadruple: this construction gives the cassette optimum lightness and reactivity. With appropriate rings and adaptors, the N3W freewheel body is compatible with all the 12-, 11- and 10-speed Campagnolo groupsets available today and in the future.
