Ok, after reading all of these letters from experienced cyclists, I'll admit that I'm just a fat old fart who mainly only commutes. But, I continue to commute on the ice with no problems. I thought most commuters were really into safety, with all the talk of helmets, hi-viz, lights, etc. WHY, oh, WHY won't you people try studded tyres? I've mentioned this before, and was basically blown off because, "our weather isn't as bad as yours", yet here are 6+ pages of letters from people falling on ice! I'm too old to risk the injuries that some of you are willing to take. I have my studded tyres mounted on a spare set of rims. It takes less than 5 minutes to put them on if things look icy in the morning, and I've had them on and off on an almost daily basis for the last 2 weeks. Today was nice, so I used my slicks, but it rained all afternoon and evening, and is supposed to get below freezing, tonight. I'll probably head out to the garage in the morning and put them back on for the morning commute. I'd still rather ride slower, than drive a car.
My philosophy is, "if you don't want to ride safely, then don't ride." (Biting my tongue, because I'd LIKE to use a little stronger language).
pant...pant....ok....calmed down, now. OK, this is the last I'll say on this subject for awhile. But, PLEASE be careful, Folks.
