I am installing a Shimano 105 drivetrain on a new bike and would like to install a brighter appearing chain. Brighter in appearance than the dull grey stock 105 chain. Any recommendations?

Thank you.

I've had good luck with KMC chains and SRAM chains on Shimano components.

But I have mostly 6-8 cog rears here, so I couldn't advise you on anything narrower.

I use KMC and Shimano chains interchangeably on a Shimano Ultegra 10-Speed drivetrain. In my experience, the Shimano chains result in a more quiet drivetrain than when I use KMC chains.

SRAM makes some nickel plated 10 spd chains that work well with Shimano. I have always been a SRAM guy though so I am biased, I just seem to have better luck with them.

Most chain companies make Nickel plated chains, SRAM and KMC's quick links make taking them off
to clean them, easy.

Another vote for KMC for brightness, as well as a quiet ride; I've found they're less expensive but I don't get as much life out of them as a SRAM or Shimano.

+1 on the quck links. Wippermann also makes stainless chains with quick links.

Shimano IG 70's are nickle plated, shift,and wear well, however use a SRAM or KMC quick link to avoid the Shimano pin connector fun. When needed it's also easier to break the chain using the quick links.
Cheers

Best chain I have used bar none is the KMC x10sl. I got about 4k miles out of it. You can get it in various colors as well. A nickle colored variant should run you $40 bucks or so. Amazon is a great place to look.

And get a Park Chain Cleaner and the Fluid for it ,no reason to be going for a bright plated chain

If you are not going to keep it clean ..

^^^^^^^I second a good cleaning set of tools and degreaser. Besides, every good cyclist should have these items.
