But I'm also not too concerned about rim wear because I view rims as a consumable.
Further, 10,000 km is a very long distance. When rotating through 7 different bikes, it's several years of use before replacement.
That's between 12 and 18 months here at roughly 600 to 800km per month which is 30 to 40km per day commuting. Maybe your rim brakes were weak? What reasonable urban or suburban person with a family owns 7 bikes for themselves?
