I had an IP-036 for nearly 3 years, put several hundred miles on the frame, sold it about a year ago, and it's still going strong with the second owner. The frame only cost $700, not $3,000 like the big brand frames so for me, spending 1/4 the cost and still getting a decent frame that didn't give me any troubles was worth the effort. Not saying there haven't been some buyers that haven't been 100% happy with the IP-036 but my experience was a positive one. The only reason I sold my IP-036 and IP-056 was I wanted something different that, at the time, wasn't offered in a Chinese frameset.
