Good price considering what stems in lesser condition have gone for recently. Question is, is it actually 22mm (and french) or 22.2 and the seller is slack with their measuring? I don’t care enough to ask.
It’s odd that it doesn’t have any Cinelli stamps or badges but sometimes they did sell off excess stock unbranded to bring a few $'s in. Also, if Eddy says it’s exactly the same as Cinelli’s branded offerings then I’d believe him. This stem is prime for someone who has a stem badge (even if a repro) and drills/pins it onto this stem.
Price is relative. If it had a Cinelli stamp or badge it would fetch 2 or 3 times the buy-it-now. What you’re buying is a mutant or maybe something someone made at the factory and sold out the back door. That happened a lot too.
Could be … I’ve seen plenty of Cinelli 14’s that are original (never rechromed) and have no stamps. Anyways, the dude who used to stamp the bars never ate breakfast, and couldn’t have given a shit about his job. All the stamps are pretty faint.
