I remember having a Cinelli stem stove enamelled black years ago instead of buying a proper one and looked mint
but 6 months later it was chipping around the stem shaft and around the holes were the bars go through,
the paint even coming off around the allen key bolt holes, worst still I was a bugger for holding the centre
of the bars and my wrist watch started to scratch the left side.
It looked very nice at first but soon got stripped back to original.
