---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- ■2x12 speed crankset from the ROAD component "ULTEGRA" series. ■Rigidity, strength, weight, and rotation performance are all optimized. ■Hollow Glide construction reduces weight while maintaining strength for better power transfer and faster, more accurate front shifting. ■Front double, rear 12 speed compatible. *Bottom bracket is sold separately.
