I've been riding in the winter for 3 seasons now, but it's been limited to riding to the train station and then riding from the train to work, - maybe only 1 or 2 miles total. I've used my MTB with studded tires from Nashbar which I've had mixed experiences with. They're fine on ice but handling is terrible in the couple of inches of slop that often ends up on the side of the road after a fresh snow.
In the last 8 months or so, I've been commuting all the way in to work on my road bike and love the additional speed I get over a mountain bike.
So now I'm wondering what to do for winter. Would a narrower studded tire on a road bike be better for speed in good conditions and traction in the slop? Could a narrower studded tire on my MTB be the answer?
After three years of even that short of a ride each day, the salt has taken it's toll on the components of my mountain bike. Even though my road bike is no multi thousand dollar featherweight, I'm reluctant to subject it to the same abuse. I should also add that my old road bike has down tube shifters which probably isn't the greatest setup for poor road conditions.
