Just polished off this model of my personal bicycle. While it’s rather accurate to the real thing for the most part I did make a few customizations such as the shield on the front of the bike, the product name and, believe it or not, the real bike’s frame is constructed from aluminum rather than adamantium
I took over 80 reference photos of my bike whilst modeling. A few areas are basically guesses though, the back of the derailleur for instance, I had trouble being able to see what it looked like and I wasn’t about to take apart the bike to get a good shot :). All in all I would say the derailleur was the single toughest part of this whole project, but am quite pleased with how it turned out.
This scene probably took a good month to build and includes 337 objects, the chain has about 120 or so links. Rendered with Cycles for 1,135 passes over the course of 9 and three quarter hours.
You can download this model from my site linked in my signature. I also uploaded the model to Blend Swap, you can grab it here.
