Prestacycle UniBlock PRO Gravel Cassette - 11-Speed, For HG 11 Freehub, 11-42, Silver

Prestacycle UniBlock Cassettes are a single-piece unit exquisitely machined from a solid block of cold-forged Chrome Molybdenum alloy steel, then heat-treated, tumble-finished and electroplated for added durability and low-friction operation.
