Hmmm
Last year was not so windy. i had 30 ish rims on (ie my normal wheels) and had no issues.
I now have a set of 60/80 wheels....and i am not sure whether to use them.
If its a massively windy day i might be a bit unhappy.
I was going to take some advice..... if i can fit both wheels in my bike bag/ the missues then ill take both and decide the day before.....
If i am taking them then ill practise a lot with them first in windy conditons.
If i could have found 40s then i would use them.
