chain worn to 1.0 - can I just replace the chain?

[Mazz]

Last time round, I fitted the cassette and chain new at the same time (10 speed). Just measured the chain wear with a 'drop-in' Park tool and it's on 1.0 already.
Do you think I can get away with just replacing the chain?
I guess I'll just give it a go and see if the new chain/old cassette mesh OK.

I change my chain every year and my cassette every other year. Seems to work out ok for me.

Just try it and see.

Very unpredictable IME; but worth having spare cassette and chainring ready just in case (though you can always put the old chain back on again of course)

Almost certainly not. Just crack on with the cassette and chain till it starts jumping - on the sprocket you use most. Then replace both. Be aware that running both on like that will increase wear on the chainring you use most cf 'normal', [edit to add] and the more % the chain is elongated the more wear you'll experience on the chainring.

It wont start jumping if you use the same chain. It only jumps (skates over the top of the sprocket) if you put on a new chain on a worn cassette. There are some caveats to vary from the above, but those will all be unique situations not applicable to everyday riding.

Yeah that will work, but it is overkill. Cassettes are expensive and most of us want maximum life from them before replacing. Also, chains don't count years. They don't care. All they care about is revolutions x load x the coefficient of hygiene.

Update: fitted the new chain today (new cassette waiting in the wings, if needed).

I've always struggled to remove the power link, then I saw this "diagonal squeeze" method which works like a dream.

Good trick, I would be concerned about damage to the adjacent links. Link removal pliers are available for not very much on many sites.

+1 for link removal pliers

Surely chain and or cassette replacement should be done on use/mileage/wear rather than time unless you are riding same amount in same conditions. Entirely your choice of course but I go on milege as a guide and more importantly measured wear.

Yeah I'm a commuter so my yearly mileage is pretty consistent. I also do it yearly as it's easy to remember and do it beginning of spring as that's when I start to cycle more and feels nice to have a fresh setup.

Just easier to remember, plus it's always knackered at the end of winter, and no point changing during winter.

Yes but no point in changing unless needed plus of course if only done on time not checked wear then could potentially be overworn.

Anyway, your choice your cash 😉

There is also a old shoe lace trick, but you'll not regret specific link pliers. I have some that split and join the chain. So much less faff !

1) it's always worn at the end of winter
2) sure, but you only wear another one anyway!
