I just put on my 3rd chain on my bike. i get c.5000km out of a YBN 11s chain using immersion wax. Probably 5500. Less than 6000km. I change it when it gets to 0.5%, not 0.75%.
Curious how much life people get from their setup.
A YBN chain costs c.20 eur, and the wax has no additives, so it's probably c.10 eur/kg or so, maybe 15, i dont remember, once you factor in shipping or what not. 1 pot of wax can do 10,000km, arguably, idk.
