 The same width as the 11 Speed cassette meaning total compatibility with wheels and frames 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 The two largest triplets in a single piece which reduces energy losses Special surface treatment increases durability and improves smoothness Closer sprockets ensure faster, quieter and more precise...
