I want better traction on ice & snow

From the experience of Leon:

"If you're going to ride in really nasty conditions, get something to give you some additional traction."

Tyre Grip is a spray that you apply to your tires. "The ad says it increases traction by 300%. I believe that's true. When doing the math, no traction increased by a factor of 3 is . . . well, still not very much, but noticeably better. I carry a can on each of my bikes. I've been using it for about 10 years or so now."
