spare wheels

[BrindiCruiser]

G'day,
I bought some new wheels recently. I transferred my cassette to my new wheels.

I was thinking of putting another cassette on my old wheels so that I can use them as a spare wheels. However, I think that means that I will need to source a cassette with about three thousand k's on it cause a new cassette would prob not mesh well with the rest of the drive chain.


I was figuring e-bay, checking with mates and LBS.

Any other ideas?

is that 3000km on the one chain?... time for a new chain.

if you replace the chain now your cassette will last a great deal longer and you wont have to worry about getting a worn in cassette... which in itself wont work either as the cassette works into your chain... not someone elses.

even if for some reason you didn't want to get a new chain i think your a new cassette should work fine.

somewhat messy answer but i hope its understandable

The simplest answer would be to leave the old cassette on the old wheels and have a specific chain to go with it. Which means that in turn you should get a new chain and cassette for the new wheels.

Just to make things more complicated you should rotate chains as well. This will siginifcantly extend the life of you cassette and chainrings.

hmmm

I understand the idea of rotating chains. It is one of those things that nags away at the back of my head. I keep thinking it is time to get another chain on to extend the life of the cassette and chainrings.

I even bought two chains when I lasted changed over the drivetrain on my MTB. Still have not done it though. DOH!

I am not keen on rotating chains and cassettes cause I think I would be even less likely to do it!

However, if I put the new cassette and new chain on the new wheel after a while they will all wear down.

I was kinda hoping to find an oldish 10sp cassette to put on the old wheel for the odd emergency use! I figured that would be reasonably cheap.

Yeah the best option would be to buy a new chain, you can get some pretty cheap ones of the net, depending where you are.

Rotating the chain and cassette will give you a better life span, but if you want to get a new cassette you have to make sure that it will be smooth enough, otherwise you will end up having to buy a new chain anyway cause of the jumping.

Otherwise i think you can get some BBB cassettes fairly cheap too, which could be an option cause they are new, or if its only for emergency just get the bottom of the line cassette cause some of those are really cheap.

rotating cassettes on a chain isn't bad news... the idea is to keep your chain new... if you do this you'll have no problems.

an old cassette needs an old chain
but a new cassette can go on an old or a new chain.

if you were to ever get a new chain with the old cassette the old cassette will be redundnt.

Just got a call from the bike shop (which is trueing my wheels today).

Looks like the existing chain and cassette are end of life after 3500k) I think I will just keep riding them until I find the shifting performance annoying (which is not yet).

Then I will get a new drive train with an extra chain and cassette to rotate onto the extra wheel.

Must remember to buy drive train before actually I need it.

You'll wreck you're chainrings as well if you do this.

I was planning on buying a new 39t chainring at the same time cause I assumed it would be cactus if the chain and cassette are buggered. I was going to leave the 52 cause I don't spend much time in it.

Sounds like you think chainrings might last longer than chains and cassettes. That makes sense to me cause there are more teeth engaged at any one time, so I suppose that spreads the load.

Tis a sh### having to replace drive trains. Definitely not a sexy part of your bike to spend money on.

you should be able to go through at least 3 chains to every cassette on a roadie.
and a few cassettes to every chainring
