I was browsing around ebay looking for a replacement for a 3T stem that was slightly too large for me and came across some 3T carbon stems where the price looked "too good to be true." I immediately asked the seller if they were authentic and they said they were not but promised me good quality. Anyone have any experience with stems like this? I don't own anything that isn't authentic but I wonder about these.
