The GL330 rim on the Nômu Lab Wheel No. 33
↑The entire rim is anodized and has turned gray.
This is done to improve surface hardness and corrosion resistance,
There's a marking indicating that 650 watts of electricity is applied during the anodizing process.
↑This is the GEL280, which is lighter than the GL330,
But for some reason it says 650 volts instead.
↑This is the Paris-Roubaix SSC, but the typeface and the M logo are slightly different,
so it appears to be from a different production batch or era.
One shows volts while the other shows watts.
Logically speaking, 650 watts = 1 ampere × 650 volts.
It's unclear why the markings are inconsistent.
