Chain needs replaced

Postby roverthehill » Wed Jan 02, 2013 20:51 pm

Hi,
Bought one of those chain stretch checkers:

and it looks like I'm overdue a replacement. The current chain is imprinted with KMC, Super Narrow and Z. So i assume it's this bad boy:
http://www.chainreactioncycles.com/Mode ... elID=24701

I have a couple of KMC powerlinks so should prob stay with KMC.

At near 50 notes, It doesn't seem too cheap so is it worth the cash or are there other 9 speed chains that would do the business?? Apologies if this is a daft question!!!!

Also, in terms of the rear sprockets - it there a tool to measure the wear on them?

any 9spd chain and same speed reusable links will be fine.

cheers nick. I think I posted the wrong link. it's looks my current chain is an older one:

which seems cheaper. Not sure if it's still available so I guess i can go with any 9 speed with decent reviews.

If the chain is stretched to 0.75 the rear sprockets should be OK.If it's stretched to 1.0 then the chances are the rear cassette has worn with the chain and will need replacing.The front rings may also be shot.Depending on conditions etc generally I get 4 chains to a rear cassette if I change at 0.75.
IMO expensive chains are a waste of money unless you're a weight-weenie or into bling :roll:

like i said ANY 9spd chain.

buy what you want.

cheaper and often is better.

and if your old one was very warn expect new cassette as well.

and is there anything to determine cassette wear?

From this guide it seems visual inspection is the way to go:

No a cassette can look fine too the naked eye.Generally if the chain is worn to 1.0 then the cassette is worn too.

cheers guys. In terms of replacing a chain. i assume I need one of those wee devices to open up the chain- are they specific to 9 speed chains or universal? The chain is greater than 1 mm so the cassette probably a gonner - doh. Are they universal too? Just use any 9 speed casette?

it looks fairly easy to replace - but gonna need some tools :( too.

£11 job done.

If you need a cassette CRC have Deore for £14.99.

Sorry to jump on somone else's thread, but it seems on topic.

If my chain has been slipping a lot (happening more and more) is it likely to need replacing? Been waiting for a chain whip to come through the post to fit another cassette, but thinking I may need new front cogs too.

if it's slipping it's probably shot.You'll probably need a new cassette but might get away with replacing the front rings.Try a chain/cassette if still slipping then replace the front rings also.

Thanks.

Been buying loads of bits to fix my bike, wish I'd just given it to the bike shop now :cry:

Any advice on a standard chain, or how to identify my current one? It's a standard set up, 8 cogs on the rear cassette, 3 at the front. Thanks!

You don't need to, just buy one labelled 8 speed

They would have charged you more for the bits anyway, plus labour.
Just find a cheap KMC 8 speed chain. CRC or Ebay. The cheaper ones are a bit heavier but last.
