just ridden leeds bike park on a red bike. boy was I flying…. ;o)

Not necessarily, but faster bikes are red.

Yes, of course. But white bikes are lighter.

Well, I’m not saying it is conclusive, but my red Stumpy full-sus feels slower than my Merlin Malt2. That could be due to the tyres though.

Why is is always tyre choice?

Yes. yes there are – My red Devinci Troy is a lot faster than I am!

One of these? Check your front basket for stowaways.

Red is the fastest colour known to man so a red bike must be faster than any other colour bike.

I am colour blind.
What is red?

My yellow Slolaris was faster than my blue Meta AM at Leeds bike park, so I sold  the meta!

Make of that what you will…

Yes, of course. But white bikes are lighter.

Actually, white and yellow are the heaviest, the lighter colours have thicker paint. Obviously a raw/polished finish is the lightest.
Lightest isn’t necessarily fastest though, so yes, red ones are quickest.

My red DH bike is faster downhill for sure than my black trail bike. My black bike is faster uphill unless on a chairlift or cable car in which case they climb at more or less the same rate… It seems more confusing than I first thought. 🙂

I thought the laws of physics had changed, and satin black was now fastest, or ‘stealth’ as it’s known?

ever since I almost got run over at a crossing on my bmx as a kid by a red seirra car I do not like red.

My apologies. Glad you are enjoying your new bike.
