My last post was an error, rushing myself. However, cherry picking quotes is some weak tea.
There is no 180 in my posts, only a poster in this thread twisting other peoples words in an effort to support their own failed point.
Today's post:
my forehead is bare skinand that's the point of wind chill factor, how the wind can affect exposed skin. So, wind chill factor works for bare skin, but ... and I repeat what I've said a ton ... when temps are low enough to consider wind chill, you'll have very limited skin exposed while riding a bike, so it's pointless.
Read the OP: For rides when it's cold and windy, simply include a wind blocking layer and dress the same as you would for the air temp. Wind chill is about the lose of heat from exposed skin, and I don't know anybody going out with exposed skin when temps are cold enough to consider wind chill.
BTW I'm going out for a 20-mile ride at 2F/-17C ... it's an errand, not a commute, I hope that doesn't offend someone.
