Rondo Ruut bicycle (free model - link in description)

This project is inspired by awesome works of Guillaume Bout.
After a very long break, I've gone back to rendering with Cycles and I must say I'm amazed how well it performs.
Feel free to download the .blend file and use it for any purposes, just please don't redistribute it as yours.
Also, consider crediting me if you find my work useful.

Please keep in mind:
1) Some of the textures are missing - I needed to delete all commercial ones. I've marked the missing bitmaps with red colour in the node editor.
2) Some parts contain custom vertex normals which may cause shading artifacts when rendered with a different engine.
