What I'm trying to figure out is which model my bike is. I got it from my brother who bought it used and knows nothing about it.

It's a Tommaso brand. That's all I know for sure. Has a carbon front fork and has 6061 aluminum written oj the rear stays in bold white letters. The bike is a Matt black finish and looks to be original. It has shimano shifters and derailures, Tektro brakes, and joytech wheel hubs. Wheels look to be unbranded.

I'm not sure if any of that is original for sure, but it looks to be so. Any help here?
