This of course will vary depending on conditions and drivetrains. With SRAM RED 22 chains we have reports of people riding 300-500 miles between application….same with 11speed shimano dura ace chains. Personally, we like to apply wax every 5 hours of ride time. Since no two chains are the same it’s difficult to assess over the internet…however we do have some more aggressive application methods to help the wax penetrate into the chain for those stubborn rollers. We always say to use sound as an indicator of needing to wax again.
