Hello, I’ve had this fixed gear for a long time and never knew the brand of it. A friend left it at my house and never decided to pick it back up and that was 10 or so years ago, never got a brand name or anything, I’ve since painted it blue and sanded both stem and crank to bare metal to give it a different look, had a Shimano BB-UN51 sealed bottom bracket and I believe its original because it was really seized in there, I would love to know the brand so I can buy frame stickers and stick em on there, I’d really appreciate any clues or if you know the brand, thanks
