Have you ever had to pry off your cassette because it had dug into your alloy freehub? You’re not alone.
NOVATEC has solved this problem by inserting a small steel spline onto their freehubs. They call it Anti-Bite Guard. The ABG steel spline stops the cassette from seriously damaging your alloy freehub body.
If your hub didn’t come with an ABG freehub, don’t worry, Novatec hubs are backward compatible and they will fit on your existing hub.
