Subject: RE: New Cassette Questions?Campy cassettes with an 11 tooth cog usually come with a lockring. Campy cassettes that have a 12 or 13 as the smallest cog usually do not, however you can use the lock ring on your your current cassette for these cassettes.
All the Campy cassettes or all levels are compatible with all the various Campy groups so long as they are the right speed (9 speed vs 10 speed, etc. ). Mirage is the lowest level, but is not substantially different from the Veloce cassettes. The only difference is that the Veloce cassette has a nickel plating that makes it shinier and possibly adds some wear protection.
You probably won't need to change out the chain because of the chain length difference. Going from a 12x23 to a 12x25 or 13x 26 is not a very big change, but if the chain is worn you will want to change it out just to prevent excessie wear on the cassette. Just measure the chain for wear. |
