11t question

[fattywilliams]

Bought a 2nd hand sram cassete as it was lighter and offered better range for what I wanted unfortunately its slipping very occasionally in the 11 question is can I swap it out for the 11t sprocket on my outgoing cassette that is sihminao tiagra. Both are 10 speed cassettes

Do you have an 11 tooth compatible lock ring on there? Shimano come in two sizes.
Other than that, no problems.

Yh def a 11t lock ring so should be alright then?

Yup spacing is the same and there are virtually no shift gates at that end of the cassette anyway.

I've probably done it before now by mistake and not noticed with the number of cassettes I've got lying about.....

Try it and find out?
