I decided long ago that if I need a balaclava on a bike, it is too cold.

The bodies internal survival mechanism concentrates heat to the vital organs and sacrifices the extremities, that's why your fingers and toes get cold first. People will put on socks and gloves when in fact what the body needs is more insulation around the core and head.
The majority of heat loss is lost through our head.
In any survival situation where hypothermia is a potential issue the last thing you want to do is work up a sweat.
As for the OP, you need a rain shell to prevent the rain from getting your clothes wet and wicking heat from your body. But the fact you are riding working up a sweat is also problematic. Get a bike trainer and ride indoors during cold weather.
