I know a lot of you here run SS/FG bikes in the snow. With where I live and the commute that I do, this is not an option, so I'm looking for the best gearing for my hybrid with 700x35 tires. I'm not so worried about the high gear, but I'm wondering about the low gear. I wouldn't want a gear where I would have no traction because the tire would just be slipping and me getting no where. So what's the best low gear to have for climbing steeper hills when the roads are slippery?
