The new cassettes have thinner sprockets, reduced spaces and unchanged dimensions compared to the 11V sprockets and allow to support all the requirements by offering only two cassettes of 11/29 and 11/32. They are therefore compatible with the current 11V cassette bodies and frames. The closer sprockets ensure an even better gear change rapide, silent and precise thanks to the particular design of the teeth and the surface treatment that guarantees a longer life.CassetteProduct use : RoadProduct model: Record/super recordColor: SilverVarious attributes: 11-12-13-14-15-16-17-19-21-23-26-29Number of gears: ¨12Number of teeth: 11-29Product subfamily: SprocketsProduct family: Components (velo)Packaging : (sold in unit box)
