This post sends a huge thank-you to Peter at Sportcrafters. I've ridden exclusively on two sets his rollers for close to five years and logged (quite literally) thousands of miles and hours between indoor training, teaching spinning classes and race warm up. I've posted previously about how 'tired' and worn out they are from use so after a little research and a phone conversation, Peter honored his lifetime warranty policy and without hesitation he shipped me two new sets to replace my old ones. Included are resistance units on both sets so now I can do my minute long +500w repeats indoors. Thank you Peter and Sportcrafters!
