Jockey wheels 10T or 11T (9spd) ?

[Rider3000]

Hi fellow hubbers,

 

I'm not a bike mechanic but could really do with some expert advice.

 

I have a 9 speed shimano road bike and I'm replacing my drivetrain parts so i was wondering...

 

I couldn't get the 11T jockey wheels (as standard on my Road bike) but found the 10T wheels instead... on the packet it says "for Shimano 7 & 8 speed" and campac 8,9 and 10 speed.

 

After reading comments on the web I'm still not sure if it will be compatible and /or if there will be issues / sounds or extra tear for using the 10T wheels.

 

Hoping someone can explain the pro's & cons before i change it.

there shouldn't be a compatibilty problem and i doubt you'll even notice any difference in sounds/wear or performance/shifting.

 

EDIT: as long as the rd is set up properly with the "b" screw properly adjusted for correct clearance between the pulley closest the cassette and the cassette itself, shouldn't be an issue at all.

 

question is, are they really that worn? took my shimano 600 rd 20 years before it looked like it was time to replace jockey wheels. most folks upgrade purely for bling factor to i.e. with these: http://www.koo-bikes...-blue-pair.html

Thanks for the reply...

 

I will keep this in mind and check with the guy that's going to service my bike if it needs replacement, reason was i was told that it's best to replace all "rotating parts" when replacing chainring, cassette, chain etc. But will check just to make sure. Did about 40 000 km's with them and never had a problem yet...

this article may be of use - gives an idea of what a jockey wheel should look like for replacement.

while i'm at it, can't ignore sheldon brown - lots of interesting info on his site - the below is a link to his article on chain wear.
