In Oregon you miss a lot of riding if you are not willing to ride in the rain.
We had rain 35 days out of 90 on this tour. Good raingear, waterproof bags, and fenders make it bearable.
When on extended rides I clean the bikes at every opportunity, hopefully, at least once a week. A lot of campgrounds and hotels/motels have a hose bib somewhere handy. On long trips I do daily maintenance while my wife works on her trip journal. If no hose is available, a water bottle works too.
