View Full Version : Changing Sram Apex Cassette

I have the 2011 Specialized Roubaix that comes with the Sram Apex 11-32 Cassette.
gearing = 11, 12, 13, 15, 17, 19, 22, 25, 28, 32

I see on the Sram website that Apex also comes with a 12-32 Cassette.
gearing = 12, 13, 14, 15, 16, 17, 19, 21, 24, 32

If I change my cassette to the 12-32 will I have any problems with the RD and chain length.

I would love to be able to swap these two.

Thanks

You should have no problems whatsoever. The chainlength (which is properly defined by the big-big combination) won't change at all and your rear derailleur will actually have one less tooth to "wrap". You may have to refine the limit screw settings and cable tension slightly but that would be the case with any cassette change, even an identrical one.

jgjulio, Should be the easiest gearing swap on the planet.

Thank you.
Now where the heck to you find these.
I have searched the internet and it seems that this may be a "vaporgear" made of unobtanium...
Help...
