Welcome to the forums.

Wow I think that is a lot, what kind of weather or road conditions are you facing?

I only clean my chain and cassette when it rains, no joking. I though will usually ride it hard and change them once every 3,00 miles, or once a year.

I usually lube my chain once a week in the rainy season and maybe once a month in the dry season.

I haven't done much bike riding lately, sad face. But after 64 days I've graduated to crutches.
