Having gotten our first blast of winter early--snow and artic cold with sub-zero wind chills, I've got to get the last few things I need to complete winterizing my bike. (I did get out for a brief ride today after completing some chores around the house. Boy was it cold with the wind, even bundled up and my head covered.) I'm about to order the Continental Spike Claw 296. I'm planning on only ordering one for the front wheel. I electrified my mountain bike this summer and hate the idea of taking the rear wheel with non-hub motor off to put a studded tire on. I currently have very knobby tires since in good weather I ride unimproved, gravel forest roads. (I'm fortunate to live in the middle of a 2.2 million acre national forest.) This winter, I will change my riding pattern since I don't care to have any issues in isolated areas. I'll ride into town more often as well as possibly go to groomed snow mobile trails (if I don't get chased away). Does anyone else ride with a studded tire on the front wheel only? Is it a huge mistake not to have one on the back wheel as well?
