Hi, all! I kinda zeroed in on this board after realizing that this question wouldn't quite fit anywhere else...

I bought a frame for a buildup about six or seven months ago. It was a craigslist buy and looked really good, so I bought it for $100. It's carbon/aluminum, but it's got downtube shift mounts and the whole rear triangle is carbon. I'm a total noob to cycling and I almost certainly bit off more than I can chew with this project, so it would be good to know what kind of frame I'm working with. Outside of practicality, I just really wanna know what kind of frame it is. Either way, I've attached pictures of the serial numbers and such. So far, I haven't been able to find anything. I'd love some help on this!

The numbers are as follows:
3449U065
WTU 137SM0026A
ITK5F05308
TBI-1311

Thanks in advance!

Some pictures of the actual frame design would probably help to identify it like from the side, maybe a picture of the rear dropouts, seatstay bridge, etc.

Not a problem!
