This would mean that given the same chain ring sizes, a small/small would be more likely to rub, since it has less of a deflection needed to have the chain hit the large chain ring.
For the other direction (big/big) I see no reason for it to be worse, unless the making the chain narrower makes it noisier in the extreme positions.
However, I know many people (including my LBS) recommend SRAM over Shimano chains... could this lead to a noise issue?
Thanks for your reply. I've used SRAM chains in a 8 speed setup for many years with no problems. The funny thing is that i've gone for a Shimano 10 speed chain this time round. This might be part of the probem and I will consider changing. Thanks.
