I was riding a few meters behind a friend of mine at the end of last Summer, he had a jacket with zip-off sleeves. He unzipped his sleeves and stuffed them in the back pocket of his jacket while riding. I was pretty impressed. All with no hands, of course. And that lasted a few minutes. Geez.

I can ride for about ... hum, 3 seconds with no hands, and certainly not drafting. It blows my mind, too.

It's all in the core.
