Hello and thank you for looking.  Up for purchase is a Sunnywheel Light Smoked Plastic Bicycle Chain Guard Model Number SW-788 Without Hardware.  It's new, but has been out of its original packaging and has some fine scratches, so please use the pictures as part of the description...

I personally installed this chain guard on a 20" Mongoose bicycle as pictured to show how it fits, but it may or may not fit on a similar 20" bicycle.  Hardware is not included, so you'll need to supply the clamps that are shown in the pictures.

PLEASE NOTE:  You are purchasing ONLY a replacement chain guard.  The hardware and bicycle in the pictures are not included.

Shipping will be US Postal Service with Delivery Confirmation.
