Found One More!  Up for sale is a nos vintage original SunTour BMX Racing Parts Red Anodized Forged Japan Seat Clamp. The size is 1-1/8". The clamp is nos, has never been used, and comes as pictured. Has some wear and staining imperfections around the bolt area from getting wet while in storage so its not perfect but still nice. Check the pictures closely to see the condition! This would be needed for that BMX Bike restoration project! Email with questions or concerns!
