New chain rattles/vibrates(2 posts)

New chain rattles/vibratesschimanski
Mar 1, 2003 1:40 AM
I just had my chain, chainrings and cassette replaced and now
the chain rattles when using any gear. Noise gets gradually worse
towards the smaller cogs and in 11 (on both chainrings) chain's the most
'jumpy' though it doesn't skip or jump off the cog. Generally it feels
like the chain simply doesn't fit and there's a notable vibration
from the back when turining the crank forward with any force.

Shimano's pulleys 90 degree to the ground method suggests the
chain is HALF A LINK too long and I have no idea how to fix that.
Changing gears is quite smooth but I don't like the vibration, that
shouldn't be happening as far as I'm concerned.

I have Ultegra CS-6500 cassette and 105 chainrings, the chain itself is CN-HG73 (105),
which the 2003 Shimano manual says is OK with Ultegra, though the older (2001?)
CS-6500 cassette 'maintenance manual' from their website says only Ultegra and
Dura Ace chain is usable.

Using the old chain, cogs and chainring there's no vibration.

Is it simply the chain or what should I be looking at?
