After removing my cassette from my older American Classic hub, I noticed that my cassette body splines are damaged from the individual cogs indenting the splines. Do I need a new cassette body?
Many times you can save your aluminum cassette body by using a file to smooth off the tops of the scuffed splines, making the cassette easier to mount. Before the invention of the steel faced cassette body, we used aluminum free hub bodies on all our wheels. Aluminum is softer than steel and naturally display marks from the splines over time. To limit this from happening, make sure your cassette lock ring is tight and that your cassette is not loose. When loosening the lock ring always place the chain whip on the smallest cog. Failure to do so may result in damaging the cassette body splines, which is not covered by the warranty.
