The max roller diameter for a normal

#41 chain with a max roller diameter of .3125 inch. The official line is they are not compatible, but my testing with 400 miles on each of two chains on two campy 12 bikes showed no problem. The axs chain is also slightly narrower than a Campy chain.
The shifting with either chain has been flawless.
The axs chain may be too narrow to work with some 11 speed chain rings.
