I've ridden through some downpours lately and I'm curious about caring for my bike afterwards.
Typically I'll wipe the entire frame, handlebars, seat, derailleur externals and rims down with paper towels, and give the chain a quick wipe. Bounce the bike on the ground for a minute to shake off excess moisture from the drive train. Then if I'm at home re-lube the chain.
I've given up on the idea of a foul weather bike and I just ride my Ridley every day now. Is there anything else I should do to care for it after riding in heavy rain?
