Last week, I got [from eBay] a cheap carbon-wrapped alu stem to replace a Cinelli Ant. I was thinking it was going to shave valuable grams off for the same dimensions... IT IS HEAVIER. The seatpost and bullhorns I also got are appreciably lighter, so two out of three ain't bad. Assuming this isn't a big dental bill in waiting.
Even full carbon stems aren’t lighter than alloy. They have to withstand quite a bit of force so need to be built thicker/heavier
I had a carbon Pro Vibe stem and the alloy version of the same dimensions and it was about 25g lighter than the carbon one.
