They have been around for quite a while, their motorcycle tires, while less expensive than the big name in off-road tires, perform pretty well. I used them back in the 70's on my bicycle, and my motocross machines. they can be heavy, as I recall, no experience with the newer products, though. Their tubeless bicycle tires seem to get good reviews in the tests I have read, and if American Classic is alright with them, they must have something going for them.
IRC, CST (Cheng Shin, for many years,) and Kenda seem to have prices lower than the bigger names from Europe, but so many of the European makers have plants in Asia the difference must be in the cost of the name, is suppose. (Said the old guy

that buys Continental Gatorskins
