Whats the most overrated factor in determining a winter cycling layering strategy: temperature, wind chill, or perceived exertion? Is it possible that road cyclists are too focused on temperature and neglecting the other two, leading to a bunch of overheated and sweaty riders on the roads? Meanwhile, mountain bikers and commuters seem to have a better grasp on layering for the conditions, but is that just because theyre not as concerned with looking pro? Do the pros even get it right, or are they just sponsored to wear a certain brands kit regardless of the conditions?
