Shimano 600 tricolor.
Its the first great group I owned and loved the usability and as a result really like the soft gray. I get that its painted and one of the first groups to go from chrome to paint, but that gray is so nice.
There is beauty in functionality and simplicity.
Its still the group that I compare everything else to.
I dont really lust after high chrome groups. I instead like the frames to stand out.
