Well... I've ridden across a sheet of ice with street tires (I'm from North Dakota... if you want to ride more than 6 months a year, you have to be brave). I've ridden when the ambient temp was 29 BELOW ZERO. I've ridden in 30 degree weather on SuperBowl Sunday to go to a tubing hill and play in the snow. But I think 29 below beats most everything else. It's dicey riding in nasty rain, but if it gets too bad, you pull over and wait it out. The only way to wait out 29 below is to pull over for a month. LOL
