I bought this bike a little while ago because it was a cheap carbon bike. The old shimano 105 9 speed components were a little worn and not shifting as well as I would like so I wanted to upgrade them. The ISIS drive bottom bracket was also starting to creak a bit and wanted to see if I could replace it with hollowtech II. I also wanted to get some new compact drop bars and the wheels were out of true.

The wait-time on buying a new bike right now is about 6 months and buying a new carbon bike is prohibitively expensive so that was out of the question. I decided to install a brand new Tiagra 10 speed groupset and restore the rest of the bike. 11 speed would have been nice, but I would've had to buy new wheelsets.

There was also a small chip in the carbon fork from a certain ahem accident I had on the bike last year that I wanted to fix with some basic carbon bike frame repair. The carbon damage was mostly cosmetic. If the carbon fork was cracked I wouldn’t have tried any carbon repair and probably would have just replaced the fork. Carbon bike repair can be risky if you don't know what you're doing, but this fork was still in good enough shape to be repaired.
The original bike was a 2005 Giant OCR Composite 3 and had all of the original components on it when I purchased it.
