It hard looking at the picture ? - does the seat tube go smaller at the top ? (change in size about half way)
are the forks air bladed - tear drop shape
read drop out has the serial number on it - some started witha T
I think it might be a JEN MIN frame and forks
here is what mine looks like - some came with a bit of gusset plates
hope this helps - if it's a tange then it also could be a RATTLESNAKE
cheers B
