no idea. never had that problem.
i guess it could be something with breathing and/or your nose getting really dry from heavy breathing and lots of airflow.
do you have the problem also when running?
i guess it could also be something with vibration...
or maybe because when you ride your nose is more downward angled than "normal" or when running or something... maybe fluids or something flow down into your nose when you ride???
