I was walking to the supermarket yesterday and saw three roadies riding out of a driveway heading out for a Sunday afternoon ride.
The temperature was ~55F (13C) and sunny so I was wearing shorts and a long sleeve t-shirt. The roadies looked like they were expecting a blizzard. They had leg warmers, tights, heavy jacket or wind breaker with a couple of layers underneath, and one guy wore a balaclava.
When the weather is like this (or even colder) I've seem commuters (including myself) wearing much less and they were comfortable.
Ok, now comes the can of worms. Are all (non-commuting) roadies wimps?
