Re:
I think I'd rather have a few extra shifts from my di2 than use power to pick a bar colour.
A bit pointless and a huge gimmick I'm sure will cost a few extra £ for precisely no gain, in fact imho, loss.
Hope, hang your head in shame. Why not spend some time researching a light and robust freehub instead (stop using metallic coloured cheese)? A way better and actual problem that needs solving. Oh, and that weight you saved by buying carbon bars, it's just been added back by a battery at each end. I hope you don't get caught out in public when the batteries run out. You are going to look soooooo silly with plain carbon bars.
Wtf? Maybe it's a few beers talking, but this actually angers me.
The bar will still need painting/coating in some way to protect it from UV.
