Hi,
The rear triangle on my Look KG481SL is white and I have had a few white components over the years (including a rear derailleur) and I don't like white paint on bikes.
White looks great on a bicycle when it's clean which is almost never if you actually ride the bike.
I'd repaint my Look if it was feasible but I guess I'll keep using exorbitant amounts of diluted Simple Green to keep it reasonably clean.
