Carnielli stems
 

Put this stem on my Rickert. It came off of a 70's Bottecchia. I remember seeing these on Atala, Frejus and other Italian bikes of the Boom years. Theyre nice looking and will accept Cinelli bars. A good quality vintage looking stem.

Me and the Rickert, one sweet ride.

Carnielli was the manufacturer of Bottecchia so many Bottecchias came with them. Probably Graziellas, also made by Carnielli, and the odd Carnielli branded bicycle too. It would be interesting if they used those on other brands as well. I don't remember seeing that but maybe.

Oh, so thats why it says Carnielli on Bottecchia frames. Perhaps these are unique to Bottecchia. I seem to remember something very similiar to these on other Italian bikes. Could be I'm thinking of older TTT stems.

Yes, 3TTT did make very similar stems which were also often used on Bottecchias and other Italian brands. Carnielli was a major Italian bicycle manufacturer who produced bicycles under the Bottecchia, Graziella, and Carniella brands. I don't know if they manufactured the stems themselves or had them manufactured for them by someone like 3TTT or ITM but they are nice "faux lugged" stems. They come in two versions: the early one like you have has the exposed bolt on the top, the later one used a recessed 7mm hex key bolt. They sometimes crack where the expander plug fits in the bottom of the stem but you probably wouldn't even know it until you took the stem out.

The Italian brand "FG" looks somewhat similar too.

Also Amica, Annabella and Roma-Sport.

Interesting. I've vaguely heard of Roma-Sport but not the other two at all. A while back I ran across an oddity of a Graziella racing bike. Until then all of the Graziellas I'd seen were the folding model but this one is essentially a Bottecchia but with Graziella head badge and decals.
