    If you are talking about Shimano then the answer is you need the spacer at the back. The lockring at the front has a built-in spacer. Don't know what other spacer you are talking about. If the hub is a MAVIC you may need a 2 mm MAVIC spacer all the way in the back.

    +1. just one spacer, inboard of the cassette. And, yes, if it's got mavic hubs, you'll need the crazy-looking spacer behind the shimano one. The reason for the spacer is the fact that the 10cogs are actually narrower, as a unit, than the 8- and 9-speed cassettes.

    That thin washer under the lockring is there to make it a bit smoother and easier to remove the lockring. Be sure you get the lockring tight enough. Loose cogs are not good.

    8 speed to 10 speed

    thank you al1943..I guess I'm all set. I changed my bike from 8 to 10 speed.. crank, b/b. shifters and cassette next to the shop for a 10 speed chain( I don't trust myself to install a new one.) I hope the r/d works because I went from 12/25 to 12/28. thank you guys for your help.

    the 28t cog should not be a problem for any Shimano r/d. What model are U using? Also, what shifters are you using? Friction downtube shifters should be fine, but indexed shifters need to be 10 speed.

    Seriously? Compared to everything else you did putting on a new chain is a piece of cake.

    Question: are chain rings 1 size fits all? Will the cogs on a chain ring used with an 8 speed cassette be too wide for a 10-speed chain?
