I have been thunking about rollers. Lenny posted this; Studded Tires- BikeTiresDirect.com Snow tires for bikes I am wondering how much these would enhance the friction of a friction drive. Not all that expensive.
Thanks Lenny. I was wondering how to DIY snow tires. I live in CT and ride most all of the winter
