edcos Monoblock is, in a word, a piece of art: A single-piece cassette exquisitely machined from a solid block of cold-forged chromoly steel, then heat-treated, tumble-finished and electroplated for added durability and low-friction operation. Shifting ramps and profiled teeth provide smooth and consistent shifts. Its honeycomb design allows for maximum material removal while maintaining strength.
