Please enjoy shopping with peace of mind! -------------------------------------------- 【About Included Manuals】 If a manual is included, it will primarily be in Japanese. We recommend using image translation apps if needed. 【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. -------------------------------------------- Compatible models Cygnus Griffith: (SEJ4J) BKG all models | Jog 125: (SEJ5J) BKR1 Free length: 117.5mm Outer diameter: 57.8mm Load during use: 531N Normal ratio: 15% up (Cygnus Griffith) | 17% up (Jog 125) By strengthening the spring, the WPC clutch center spring encourages the pulley to shift gears in the torque band, and quickly and forcibly returns the pulley, which was previously in a high-ratio state, to a low-ratio state when suddenly accelerating from deceleration or on a slope, resulting in sharp shifting characteristics.
