Open to any brand, any year, and any model! Looking for a 58CM! Let me see those bikes!
Haha, I think you know where I’ll refer you! 
I know its not a 58, but I have a 56cm Felt DA thats highly adjustable. I’d be willing to sell just the frame or the whole bike. Let me know if you’d like more info!
See my F/s thread. 2012 XL Speed Concept in excellent shape.
Would a 56cm Cervelo S5 fit you? I have one listed in the classifieds.
Titanflex Al-Ti frame with Titanium beam for $500. Like new condition. Black with silver lettering/decal.
