I have an old caad2 I am building up (again). it currently has an old 8 speed 105 group (all silver group, silver rim/spoke wheels) and is getting sram rival (all black) with a carbon force crank and my old aksium wheelset (all black).
I for one am kind of tired of all the silver. I have an optimo with 7800 and think the crank is the the worst (aesthetically) part of the bike
