Exactly what JP says.hugejp wrote:From my experience the pics above are for steelies (the plain nut "L0A") & grx mags (the washered & collared nut "J0A").
I switched from mags to steelies on my 4.8 grx & had to change nuts too.
From what I understand, the L0A is not for the alloy mag, but for the steel rim.
Be warned: running the wrong nuts with the wrong rims can cause ueber nonsense...
