Re: Rainy ride-
I'll bet if they made a coating for a roller out of the same kind of rubber that my daughter Sophie's sticky lizard is made of, it would work. It's that kind of sticky rubber where, if it starts to lose adhesion, you can just wash it with plain water and it gets sticky again.
But I don't know how durable the stuff is, as far as applying torque to a bike tire and surviving.
