Just to add a note of heresy, I’ve used Mavic Ksyriums for 8 years; the rear died last year, only because Mavic no longer had the rims in stock.
I’ve just done the 3 peaks on Ksyrium Elites, and am still using Mavic Heliums from 10 years ago on my good road bike.
Well built wheels will last, and Mavic seem to be well built factory wheels.
I’ve also got the usual lazy response wheels; open pros on Ultegra, and they are still going strong, but are only 8 years old.
Weight is wildly over-rated in terms of wheels; light is desirable, but will make little actual difference in performance, largely because the difference between ‘light’ and ‘heavy’ is ‘not very much’.
