SUPER RECORD 12 SPEED Sprockets; New Super Record 12 Speed sprocket packages: thanks to their unchanged dimensions and full compatibility with wheels and frames, they offer the user considerable advantages. Campagnolo's focus is always on the cycling enthusiast, with the aim of improving his performance and making the impossible possible. Adding a new sprocket sounds simple, but it certainly wasn't easy to do it without changing the dimensions and at the same time improving the durability! The new Super Record 12 Speed sprocket packs have thinner sprockets, less space requirement and the same dimensions as the 11 Speed sprockets, which means that all requirements are met with just two cassettes. The new 12th sprocket allows a linear ascent or descent, with only one tooth skipping to the seventh position and the cyclist finding the optimum gear in any condition. In addition, the adjacent pinions ensure even faster, quieter and more precise gear changes, thanks to the special tooth shape and surface treatment, which also extends the service life. The 6 largest sprockets are also available as two three-part packages, each consisting of a single steel part, thus avoiding energy losses. Thanks to the spacers of the same thickness, cassette assembly is easy.
