I have been using Rolf Wheels on my road bike for 15 years, I used the Rolf vigor on my road bike, they are fast and strong. I have hit potholes strait on before and never have any of my wheels come out of true. On the down hill extremely fast. Bearings are easy to service. One tip replace your bearings at least every other year or every year if you ride in the rain. I just bought the Rolf prima Hyalite for my gravel bike that I am building, cant wait to try them.
