Different cassette replacement

Postby Cqc » Sat Dec 14, 2013 16:21 pm

Hi all, I looked online but it wasn't on the bikeradar website, etc. basically I'm going to replace my 9 speed cassette from a 11-32 to a 11-34 because it is worn and I know how, but the 11-34 is the only spare one I have, and as I have never changed the cassette to a different kind, ( I have always kept the same range), do you have to adjust the derailleur to compensate for the larger 34t cog or not? They are both 9 speed cassettes btw.

Is it essential though, or will it work without changing it?

It may or may not, won't work optimally. Learn by reading park tools. It'll likely be a turn or two in.

I did read park tools, and it does seem to have enough clearance, thank to for your help. Whilst it is obvious what happens when the cage is too close to the cogs, though, what would the problem be with having it too far away out of interest?

You'll need to sort the chain length as it may need lengthening with an extra pair of links or may not.
