Equipment

Good day ladies and gents.
Because TrainerRoad made me stronger this winteri had to purchase a new bicycle… that was my excuse for wifey :laughing:
I try to find a clear answer about AXS chain wear and honestly for me this is not.
Old shcool Campagnolo 6 links = 132.6 was pretty simple.
So question how to do measure AXS chain wear.
Do you use a specific tool? And which one or do you have a 6 links measure.
Thanks a lot and ride safe.

Only tools no measures of wear?
