Re: Friction Drive In The Rain
The kit I have is the BMP kit that is sold at thatsdax.com. I'm not for certain what the roller size is, but I'd guess that it's an inch and a quarter. I can measure when I get a moment in the next couple of days.
The terrain where I live is pretty flat, so not much in the way of hills. Maybe the biggest is 50' high, at most. The vast majority of my riding around here consists of a lot of flat roads which are frequently rainy and windy (15-30mph winds). Most of my riding is North-South, and with the winds usually coming anywhere from NW to SW, there's always a chance for some head wind action.
