I have a problem to verify the model of the bicycle.
I have frame number - A4D58277 but can't check anywhere in Google, by which company was made.

The logo on the downtube shows some similarity to the logo on this bike: https://www.ccrracing.de/road-rahmen/13-ccr-attack-carbon-rahmen.html
I can’t find a similar looking model on that site but you could contact them at least to ask about the serial number. It seems like the best place to ask, in the first instance.
It looks to me like it’s a metal frame, road style, but current models on that site are all carbon and mostly TT frames. Could be relevant to the question, maybe it’s an older model, I don’t know the history of the company.
Googling CCR is hampered by a model of Fuji bikes with that name, the band Creedence Clearwater Revival and a model of Koenigsegg which all seem to be more famous.
We’re now looking at Quantec, so I’m parking this link here for posterity: http://www.quantec-bikes.de/page/road/race_sl.html
