However the real average delivery time is about 2 weeks to 3 weeks. Sometimes it may be even less than 2 week, if you are is in New York or big cities. I will try my best send the parcel as soon as i receive your orders. So if you will not receive your parcel in 21 days after shipment, please contact with me as soon as you can. Thanks for your understanding in advance. Very quiet brake noise enhances the joy of riding journey. Contribute to the low amount of metal in the friction material, the brake pads will do very low harm to the brake rotors. If you could buy about 10 pairs one time, i will send you one pair more as discount.
