Just because you had one set that done thousands of miles,your opinion is that they just don't crack!I see a lot more wheels than the ones I ride,I'm surrounded by them all day,so believe I'm in a better position than some to give an overview of the products in the real world,and I have seen at least 6 of these wheels cracked all over in the last couple of months,one rear only 2 days ago that had split like a banana between the nipples....try telling that rider they just never split,he was seriously injured when the back wheel jammed.
I have seen at least 6 pair in the last 6 months cracked all over
