I own a set of these rims and I am very impressed with how strong they are for being the lighter ones. I had 7 spokes blown out on the front wheel during a race and was able to finish the moto. Got back to the trailer and was amazed at how well the rim had held up. It has to be replaced BUT the track I was on was real fast and has some big jumps. Any other rim I have ever had would have taco'd before the end of the moto. Very Impressed!
