I’ve tried a lot of different pad manufacturers across many different wheel manufactures and the best I found was the Reynolds Cryo Blue. I then stumbled across Lifeline pads at a fraction of the cost and they work just as good if not better. At the price certainly worth the thy but the only carbon pads I’ve used for probably 5 years now. Read the 397 reviews at 4.6/5 average.
