Minimizing chain corrosion in winter
I got back into bike commuting this year after several years of not riding for transportation purposes. I used to be really hardcore about commuting in all weather and loved the variety of it. However, one thing I did not enjoy was how hard it was in components, especially chains and cassettes. Iowa winters with their salt and sand are not kind to the drivetrain of bikes.
Short of buying a bike with belt drive and a sealed gearbox, what are some ways I can keep the damage to my drivetrain to a minimum?
