Hi im kinda new here and i hope this is the right forum to post this. Im trying to figure out what kind of frame i just got. When i got it there were no stickers or stampeings, markings on the frame except for the id or serial number on the bottom of the frame below where the bottom bracket is. It reads 09 RADI and on the other side has some other numbers then 20.5. I uploaded some pics on here. Any help with this would be greatly appreciated thank you.
