The best way to fix a problem is to prevent it from ever happening in the first place. In this video I go over which cassette and hub combinations will prevent you from ever having to worry about damaged alloy freehub bodies and from getting your cassette jammed onto it. Pick the right parts, and you’ve won the battle without ever having to fight.

On the cassette end of the problem I like SRAM’s billet XG-1090 and XG-1190 cassettes because they have a thick alloy large cog that won’t damage alloy freehub body splines. Plus these cassettes are crazy light and stiff!

For hubs, I recommend choosing a model with either a steel or a titanium freehub body. Shimano, Mavic, and White Industries all offer freehubs in these materials only. Certain Chris King hubs can be special ordered with steel freehubs, so give us a call if you want to go that route. Whether you choose a top of the line SRAM cassette or a hub with a tougher freehub body, your problem is solved.
