TREK Cobia 29er MTB / mountain bike frame (no fork), 21" [53.5cm]

I'm selling a Trek "Cobia" 29er mountain bike frame (see pics). The frame is Alpha Gold aluminum, with butted & hydroformed tubing. Frame size is 21" (53.5cm). Rear dropout spacing is 135mm. Bottom bracket shell width is 73mm. Seatpost diameter is 27.2mm. Color is "chi red" (according to Trek), with silver and white highlights and graphics. The paint is in excellent condition, with one small area on the chainstay where the paint has rubbed off (see pic #4). The head tube takes a 1-1/8" threadless, semi-integrated (zero stack) headset (not included). The derailleur hanger is not included, but should be readily available from Trek or aftermarket suppliers (Wheels Mfg for ex). I'm selling the frame for $125 (firm, and cash only please). I feel this is a fair price for a frame of this quality and condition, and for this reason I'm not really interested in any lower offers at this time. Please message me if you have any questions, or if you would like to set up a time to meet up so you can check out the frame. Right now the frame is in my climate-controlled storage unit in inner SE Portland (near OMSI), so we would have to meet up there.
