They are fakes.
Be extra careful because the fkaes that were produced a month ago were done very poorly, the cross brace clamps were too big for the bars and would slip if you put pressure on the handlebars causing them to bend outwards.
How do I know this? Because I live in Yongkang China, and used them (without logos) on some bikes. I had to have production stopped and order new clamps for them.
This ebay guy is making a pretty decent profit margin on these too, we have contacted protaper about buying handlebars in the past and for the price this guys selling them for he'd be losing A LOT.
100% fake.
