As of today (10/9/2018), ASV levers are still made in the USA, so no "also made in China" happening with their product...yet. Although I would suspect that there could be knock-offs being made and sold by unscrupulous resellers. Personally, I do not have an anti-Chinese product stance but can say the Chinese levers I had prior to getting authentic ASV levers, did suffer from color fading (right away) and the pivot holes getting out of round after a couples of years of use. Being that they are priced so cheaply, I guess one could toss them out an buy another set and still be below retail prices of authentic ASV or Pazzo levers. I prefer to just have a good quality product from the get go, so now have all three of my bikes with ASV levers installed.
Even without an anti-Chinese point of view, I really do not like the typical Pazzo knock-offs, or even authentic Pazzo levers for that matter. I prefer the ASV style adjustment knobs (Even OEM have them) vice the preset index adjustment the former have. I like the ability to be able to fine tune the lever position versus having a predetermined position. I also like the quality of the ASV levers, even after a couple of tip overs (all three bikes) and even a low side crash on two different bikes with ASV levers, the levers never broke, they came out a bit scratched, but they never broke. Since I have no experience with the Chinese levers in similar fore mentioned incidents, I cannot comment as to how they would fare in these similar instances.
In all fairness, I actually still have my Chinese levers, I keep them in a travel bag when I go touring, just in case me or someone else in my group suffers a crash and loses a lever, so far so good with my ASVs in the past two cases. To me, the knock-offs are still good enough to use but just not my cup of tea. I even have a set of Chinese made rear sets on my 5 Gen, so again, no worries about Chinese products, as long as the quality meets my expectations.
