Tech Question Re: New Casette

fab5

Hi

Ive recently purchased a new Ultegra 6500 9 speed 12/27 cassette and fitted it to my spare wheel today.
So I took the bike for a test spin and there is a deep grinding in the bike possibly the chain not fitting the cogs on the new cassette the current cassette is a Ultegra 6500 9 speed 11/23 and when I put it back on the grinding goes???

O1. Is this a chain wear issue?

Q2. Do I need to replace the chain??

Q3. Will my old cassette give problems with a new chain?

Thanks

Sounds like u need a new chain.

Always worth checking the chain for wear.

Have a look at the alignment of the derailleur it may be that the cable tension needs tweaking to work with the cassette. Are you sure that the spacers are set up the same?

Ha... definitely not!!!
I got it build up about 10 years ago and sold it to upgrade to carbon, I bought it back as a winter/commute bike...

Right after alot of pulling and dragging a new chain was the answer

On the upside I'm now a rear mech tuning expert and also able to fit a new chain...

thanks for advice

I'll post this here rather than a new thread

The OH had a broken spoke on her rear wheel, went to her LBS and they said something about the hub being busted and that she'd need a new wheel. Then said that the cheaper wheels they had were all 9 speed and she needed a 10 speed wheel and what do you know they only had expensive wheels.

Am I missing something, is there some reason you wouldnt just take off her old cassette and put it on whatever wheel you wanted??

I'd agree with you I've swapped my new nine speed shimano cassettes onto a wheel that had a ten speed cassette on it

Brian?

Any wheel that will take a 10 speed cassette will take a 9 speed cassette. Given it's the correct free hub, Shimano/SRAM or Campag.
