Ultralight Carbon Fibre Thru Axles When we were talking about bicycle parts… We realized that almost everything is made of carbon fiber. Frame, stem, handlebar, saddles and even brake pads. But why aren’t thru axles made of carbon fiber? If we use carbon, we can reduce the weight of the thru axles by upto 60%. There were already some carbon fiber thru axles on the market, but they hadn’t become mainstream. Why not? What are people concerned about? Durability? Safety? Strength? Maybe people are worried about failure of the bonding. Or perhaps breaking from the excessive twisting forces. Maybe the current options weren’t light enough?
