ohhh. This is new to me. Whats the retail price on them? Seems to be only sold in their website and not in ali/taobao?
I think you need to reach out to them for up to date pricing. Shipping will be a huge part of the total cost, though that situation has really improved since I asked about the product. I was quoted $95 for the bar and nearly the same for shipping, but this was when there were still issues getting things out of China using EMS. I ended up getting Enve SES aero bars instead on discount.
Another option, though I have no experience with them may be the BigRock Skyline II one piece bars. They are only on Taobao right now, but since you listed that as an option they seem to be enjoying a good reputation in China.
Another thing to think about it swapping out the Kalloy stem. I run them and love them, but they arent the stiffest stems on the market.
