Mixing a new Cassette with an older chain
I have two wheelsets and rather than swap the cassette every time I change the wheelset I was considering getting another cassette. I was also considering a cassette with either 11-27 or 11-28..currenlty I use 11-25. I figured I could leave each wheelset with a cassette ready to swap out at anytime. I'm after the 27 or 28 as I want to climb steeper hills and the 11-25 is damned hard at times with a standard crank up front.
So my question is ...when shouldn't you mix a new cassette with a used chain?? My current groupset has done around 4.5k..or do I need to get my current chain/cassette assessed for wear for the best answer?
Should I just BTFU and stick with the 11-25??
All your thoughts and opinions much appreciated and taken on board.
Cheers
Rich

Bike shops say do not mix old chain with new cassette. So when preparing for real MTB ride, change tyres over from town n country to MTB. This is a bit more effort than changing quick release wheels over.
You have a different reason for your question. Will leave it up to others to ponder that.

Just have two chains and quik links on the chains, swap chains when you swap wheels

+1. Get two chains, one for each wheel.
And expect the chain to slip if you put a wheel with a new cassette on.

Perhaps the simplest solution is a hills bike and a flat county bike.
A triple on the front and a 11 to 34 on the back should take most of the sting out of most hills

The short answer is probably not to mix and match.
An even shorter answer is N+1.
Get a second bike to go with that wheelset!

No wonder you are finding the hills challenging most boats are extremely heavy compared to a bike.
Does this boat have approbate gearing for hills riding?

Is it just worth buying two new cassette's and a new chain with the same new desired gearing for both wheelset?

Conventional wisdom: issue is that chain and cassette wear together: the chain stretches, and the same time the cogs get worn down, the dips get larger, the teeth get worn back on the surface, the chain pulls against.
. As they both wear against each other, the one matches the other, even if both are worn.
Issues arise when one tries mix and match. E.g a worn down cog , a new chain on the bike - the chain will be loose on the teeth of the cogs . Or a new cog set or , when the chain is old and stretched - the chain will ride up or over the cogs and not sit down properly
If you use both cog sets about the same amount - ie both stay in the same condition - all three will wear in together. If the wear on existing chain and set is minimal - a new cog set ought to work also.
Suggest you try it and see with existing chain.
If no good, maybe get a second chain for the newer cog set.
Re the slightly larger ring size - my guess is you will get away with it. 25 to 28, 3 extra teeth, or equivalent to shortening a chain by 3 links. Most chains would take that.

Hi Mike...I hadn't even thought of the chain length... I think there's been enough suggestion that I shouldn't mix so I won't.
