Hi
I have an extra pair of 121 ceramic both in 36 holes.
They are not perfect, one has a small piece of ceramic that is missing, and the ceramic layer has pitting at some place on the other one (like many old ceramic rims..), but both are straight and free of dent.
Send me a PM with an offer if interrested.
missing ceramic on the 1st one :
pitting on the 2nd one (this is the worst part of the rim) :
