The Profile AC-2 Hub is Profile's newest hub and has the type of specs that racers crave. For starters, the cassette driver is unique as it allows for changeable P.O.E. (points of engagement). The hub driver comes standard with 6 pawls and springs. This option offers 96 P.O.E. -Maximum engagement. The other choice is to use just 3 pawls and springs. P.O.E. is reduced to 48 and minimal drag is achieved. This is a rider preference choice and both have a unique sound! Use your timing system to tune your hub for the hill you're racing on.
