Here’s what I currently know about my “bike”:
-It’s black (powdercoated from the start)
-It’s shiny and new (but old)
-Serial number is GW12L00462
-It takes a 27.2 seatpost with a separate clamp
-It’s welded (not brilliantly, I might add)
-OLD is 126mm
-It’s designed around 700c wheels (I assume)
-It takes a 1 1/8” headset
-It takes short reach brakes
-ST is 54cm CTC (with some extending past)
-TT is 58cm CTC (lengthwise) and is probably sloping
-Downtube is not welded in straight (frame is aligned though)
-Frame is quite stiff
-Tubing is straight gauge
-Frame weight is 5lbs 11oz

Pictures too! Anyone know what this might be?
