+1 for the above re tyres on road ice. Not a big fan of riding on ice, Mrs K broke a wrist and smashed her face on ice riding a heavily treaded hybrid on the road a few years ago and one of the worst injuries in our club in recent years was a guy who chanced it that the roads wouldn’t be icy, sunny where he lived – broken hip, not a killer but a major injury for him.
If you want to read about how potentialy serious an injury in the hip area can be start at page 4 post no78 on this thread;

P.S I would add I’m off the bike with a jipped back for the last few weeks so have turned into a right miserable pessimist at present.
