I have been biking in winter in Alaska for roughly 15 years. I do this when conditions are good, meaning hard trails, in between snow conditions more optimal for skiing. I use the same bike as in summer for trail riding with a couple modifications.
My mountain bike is a Klien Palomino (like the horse Trigger that Roy Rogers had except for less horse power!). It is a "dually" meaning oil dampened air adjustable shocks front and rear. It has disc brakes and is a 21 speed. It also has a specially designed pivot arm that minimizes "bobbing" action that many duallys suffer from, a fairly recent and very significant engineering development.

For winter riding, the tires I use are commercially studded for ice, similar to car tires, and are quite effective on moderate terrain.

Although special winter bike shoes are available that fit clipless pedals, I choose to use good insulated walking boots and the older style toe clips in winter.
The distance I bike varies between a mile and up to 25 miles in the winter.
All the photos on this blog were taken on a bike and photo trip I did December 15 of last year, the last time I was on my bike.
Ice is one of nature’s sculptures with unlimited imagination!
Stalagtite or Stalagmite?
