The Cogfather is the dependable second half of the Zone Pro. Think Batman and Robin, Thelma and Louise, Shaggy and Scooby Doo. A complete package of drivetrain reliability undoubtedly includes the rear cog. Machined from hardened chromoly steel and featuring two aluminium guide plates, the Cogfather is designed to not only last longer than your typical cassette, but also keep your chain exactly where it will be at all times. Maximum durability meets maximum retention.
