Road cassettes

Unique 13sp. cassette for gravel groupsets Campagnolo Ekar compatible only with N3W freehub body. Campagnolo EKAR 13sp. cassette is built on 2 separate blocks. The first (smaller) block consists of 4 sprockets, the second block then the remaining 9 sprockets. 2 materials are used for the production of cassettes: the sprocket carriers are made of lightweight duralumin alloy, for the toothed part of the sprockets, a special, heat-treated, carbon steel with nickel-chrome surface treatment was used, which significantly reduces friction and at the same time provides the cassette with optimal durability for gravel riding. Two of the three supplied cassette combinations start with a 9-tooth sprocket. Extensive comparative tests have shown that using a 9-tooth sprocket is as effective as using any 10- or 11-speed sprocket. Therefore, there is no need to fear increased friction. You will not lose any of the power you put out with a 9-tooth sprocket! EKAR cassettes are designed exclusively for mounting on the completely new freehub body with the designation N3W. This freehub has the same splining as Campagnolo 9s/10s/11s/12s cassettes, but it is 4.4 mm shorter and therefore lighter. The cassette has this sprocket set - ( 9-10-11-12-13-14-16-18-21-25-30-36-42 )
