Update: August 2022, 8,000 km, measuring 0.25% wear.
– at this wear rate I am anticipating about 15,000 km before replacement.
So far waxing has saved me ONE Ultegra Chain in cost.
The cassette looks like new; it was a few thousand km old when I went to wax.
The chain rings look great and they were 15,000 km old when I went to wax.
