New Campagnolo Ekar Gravel Bike Specific Groupset

This. I have put 9500km/6000 miles into my waxed road chains (I run 2 in rotation, for a total of 19000km ), and they still show less than 0.5% wear.(admittedly, this is road use, not gravel). Extrapolating that for cassette life, that will be several years yet, and my grandchildren may still be able to use my chainrings.
