Changing cassette

bikeit65

My bike has an Ultegra 11 speed 11-28 rear cassette i would like to change the cassette to 11-25 would all work okay after i change over cassettes?

should do (unless you do something wrong)

it may (but unlikely) need a cable tension tweak.


This is dependent on a relatively new chain.

Hopefully don't do anything wrong, :oops: i have swapped old for new in the past but they were all like for like.

If you wanna be sure then measure the chain (it should be 12" pin to pin (or edge of outer plate to edge of outer plate which is easier to do)) if it's 1/16" over then you need a new chain if it's 1/8" over then you'll probably need a new chain

The chain i hope should be fine, only 100 miles on it?

in that case i wouldn't bother measuring it.

Fit the cassette and revel in the tight ratios...
