Hello America, thank you for your comment. The frame you have is a TR frame material. TR is referred to as plastic titanium, a memory polymer material frame. TR frame has lightweight and impacts resistance and high temperature. It is colorful and has no release of chemical residues. However, it is a little less durable than metal and may fade, burn, and lose strength over time. Check here for more details: https://www.firmoo.com/help-p-144.shtml But please don't worry, we offer a 30-day return&exchange and 3 months warranty service, please click here for details.
