We have been having good weather in Holmdel lately for testing it. In the past I have used sew-ups on track and road bikes. They cut through well but spin easily if you pedal hard. Now I am using 20 x 2.125 knobby tires on my 'tank', a bike with a 45" wheelbase. They seem to work pretty well; the tread has not been clogging much. The front wheel slides now and then, but I have not fallen yet this year. Tonight could be a different story... One should avoid frozen tire tracks; fresh snow on smooth roads is no problem until it is so deep that you get exhausted riding. -- George Tomasevich, ihnp4!twitch!grt AT&T Bell Laboratories, Holmdel, NJ
