Noisy chain

Dermot Illogical

I changed my wheels, cassette and chain earlier this week. Shimano RS10 wheels, Shimano Tiagra HG50 11-25 cassette and SRAM PC951 9sp chain. The whole ensemble is very noisy.
Where might I have gone wrong?

Noise aside, I hope you're liking those wheels ;-)

The cassette should be very tightly fitted to the free hub. If it isn't then a spacer might be required. Other than that, make sure that your chain is lubed and play around with the tension in your rear gear cable. If your limiting screws are set right this could be the cause of noise in your largest and smallest cogs at the back.

I'm liking them very much indeed. Took them for a good workout yesterday and they roll nicely.

I was thinking it may be the cassette which is the culprit. Will remove and refit when I get home to see if it does the trick.

Glad you like them.

If there's no play with the cassette and it isn't a wonky fit then it's probably fine and there would be no need to remove it. I might just be the tension in the cable. If it is slightly too loose or too tight then this will effect each shift at the back and create noise. It may just need tweaking with the barrel adjuster.

It's not overly noisy while shifting, although there is a bit there. The noise is while the chain is moving. It doesn't inspire confidence in the standard of my work.. :eek:

The noise would be there when the chain is seated in the cog. If the tension is too loose then the "inner wall" of the inner side of the links would be rubbing against the cog. If the tension is too tight then the "inner wall" of the outter side of the links would be rubbing against the cog. Make sense?

Makes perfect sense now that you mention it. Will put it up on the stand for inspection later and see if it's out of whack.
Thanks!

No worries. All part of the after sale service

Maybe just double check youve fitted the chain correctly on the rear mech,make sure its running on the inside of the two plates and not on the outside of the little tab,i know it may seem hard to believe it could be done but ive seen it.

Hard to believe, eh? I've just checked and can confirm that I'm a numpty..

Bet you're glad of that SRAM chain and its powerlink to let you take it off and reroute it easily now, eh?

I may have managed something similar in the past myself

Holyboy, you should start charging for the advice you dispense

I was 95% sure that was the problem but didnt want to make anyone feel stupid;)
