DEDA Disc Rotor DISC BRAKE ROTOR Floating Steel Track AL Spidera 140mm + WD-DB140

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Floating structure prevents excessive deformation caused by expansion of the brake track due to temperature rise during braking. The slight movement of the disc optimizes contact with the pads, preventing overheating of the pads and discs. Improves braking efficiency. The aluminum spider improves heat dissipation. FEM analysis was followed by rigorous lab and road tests, which were carried out over a year in all weather conditions with professional riders. In the most demanding tests, the rotor passed a long braking test up to 500°C without any deformation. Five floating rivets on the rotor allow the rotor to expand, helping to dissipate heat and preventing deformation of the outer disc. Using FEM analysis, we have pursued the most efficient shape for the disc rotor, minimizing weight while ensuring maximum braking performance. The two-piece structure of the outer disc and spider uses a floating structure that allows a small amount of play in the axial direction.
