🚚 Shipping & Warranty

For buyers who have not prepaid taxes online, please note that the selling prices of all products do not include import taxes, tariffs, etc.

Note that if the bending device of the crank cannot be smoothly wrapped by the sleeve, this is due to the expansion of the clearance caused by external force. Use pliers to reduce the gap and make sure the gap is smaller than the aperture of the sleeve.
