I've had my Kuat NV rack for several years now. It has been awesome in every way. This thing has travelled so many miles on the back of Adventure Jeep and been abused in so many ways that it was way overdue for something to break.
There was no easy fix i could make on my own so I called the Kuat Customer Support Line. Get this: A real guy answered in English on the second ring!
I explained the part that broke, and the guy said that those straps are made out of a really tough plastic, but after years of UV and weather exposure, sometimes they will break. He asked for my address and said he would send me a replacement. This was the Wednesday before the long anticipated Cedar Cross race, so I told the guy my plan to zip-tie my bike to the rack for the drive to the race. He said, "Oh, I'll just overnight it to you."
I never noticed until this project that the NV racks use tamper-resistant screws. Makes me feel even better leaving my bike locked outside on the rack. Nice touch.
My favorite rack company is now also my favorite customer service company. Thanks Kuat!
