Gentlemen, gentlemen,gentlemen.
I've observed your continuing debate as to the comparative velocity capabilities of motorised bicycles which would be similar otherwise but for colour.
In my humble attempt to avoid seeing the matter descend into pettifoggery in this otherwise erudite and sagacious forum, I have conducted trials which have been subjected to absolute rigour and strictest observance of the scientific method.
My method was to paint Qld cockroaches each weighing 30 grams and measuring 7.5 cms , one in triumph red and one in black. ( For the purists the roaches used were Macropanesthia rhinoceri. )
In all trials , conducted under strictly controlled laboratory conditions ( my back yard ) the Red one was at least 32.763% faster.
I apologise to those who would , quite naturally, be disappointed , but that settles it.
