Will this sprocket chew up my freehub body?

No our 40T/42T sprockets will not chew up your freehub body.  They have similar engagement as an XX1 cassette.

Will this work with a 9SP cassette, chain or RD?

No, it is not compatible with 9 speed systems.

Will this work with an 11SP cassette, chain or RD?

No, it is not compatible with 11 speed systems.

Can I choose to replace a different sprocket on the Cassette?

You can take out any loose cog you want with the exception of the 11T and 13T (because they interact together).  We recommend the 17T for 2 reasons:- It exists as a loose cog on all approved cassettes- Its removal results in the lowest percentage jump between adjacent gears.
