This is true. Cold air is more dense than warm air, therefore making it harder to cycle through it.

There is some science to back this up, just cannot remember what exactly. Something to do with air pressure and humidity? I read an article that suggested it accounted for a 5% difference in speed (cannot remember at what average speed though). There's probably a psychological element to it as well, easier to feel good about riding when the sun is shining and you're not weighted down in winter clothing.

As well as the increased density of colder air there are are other important factors. The difficulty of keeping muscles warm, the likely increased drag of baggy winter layers, and the psychological struggle of riding into a cold wind. I certainly find it harder to push myself when the going gets slow.

This subject is touched upon in the book Heroes Villains & Velodromes, with regard to the one kilometer track event, colder conditions = slower times.
