Studs are genuinely safer as well.
I was skeptical for months but seeing as this is my first winter I'm going to just go for it and pick up a pair of 294's and be done with it.
Expensive but the way I see it, if they can prevent one of those spontaneous "slips" causing me to break a wrist or worse they are well worth the money. I love cycling and am interested in the winter experience but not at the sake of my health and/or well being.
