Is it necessary to use the spacers on the inside and outside of the new 10 speed cassette? there weren't any on the original 8 speed . Thank you for the best bike site on the web!

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.

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?
