The unique Edco Monoblock cassette is milled from a single piece of cold forged chromoly steel. It is then heat-treated, tumble-finished and electroplated for durability and low-friction. Shifting ramps and profiled teeth provide smooth and consistent shifts.

Its dome-like structure creates a stiff 1-piece cassette, while keeping the weight down. Example: 11-28T (11s) including locknut weights just 188g.
