Ultegra Cassette for 105 Cassette?(5 posts)

Ultegra Cassette for 105 Cassette?SteveA
Aug 3, 2002 5:10 PM
I currently have a Shimano 105 9-speed cassette (13x25) with a double chainring (39/53) and am interested in extending the range of the cassettes on both ends, but particularly to 27-teeth in the low gear. Alas, I can only find up to 25 teeth on the listed 105 cassettes.

There is, however, an ideal 12x27 Ultegra 9-speed cassette.

Is this interchangeable? Any compatibility problems other than maybe chain length?

Also, can the cogs on the cassette be changed?

The Ultegra cassette will fit right on your wheel...gogene

..just watch your chain length, you may have to add a link.

You shouldn't have any problems with compatibility, except possibly adding length to your chain.
