A question for those who are knowledgeable with KMC 9 speed chains.
KMC's web-site does not offer any revelation into the difference between their X9.93 and X9.99 chains, except for the color (X9.93 has dark inner links, X9.99 is silver all over). All other features are identical.
The X9.99 is 31% more expensive.
Is the only difference the color or am I missing something? Thanks.
