I got some Ice Spiker Pros that I fit when we have proper snow and ice down here in Derby. Never bothered bedding them in, never lost a stud yet.
Not used last year, but got used for 2-3 weeks the three winters before that. Expensive, slow, craggy and noisy.
But they save me £25 a week in petrol, I don’t get stuck behind sliding cars, I don’t need to ride anywhere near sliding cars, and I don’t have the horrendous feeling of sliding along the road headfirst towards an oncoming car that I hat before I bought them, so saving me tbe cost of damaged clothing and helmets.
Priceless!
And they make icy snow rides a hoot when out for fun as well.
