Does anybody recognize this frame? I bought this bike without a headbadge and no other decals or other ID. I believe its a better quality bike because of the components on it. It has a three piece crank with cup bearings instead of a screw in bottom bracket. The serial number is made up of 5 or 6 tiny indistinguishable numbers or letters. Aluminum crank arms and seatpost. Single speed, aluminum wheels. As you can see it has a very deep frame. Any help or suggestions would be greatly appreciated. Thank you.
