Hi
I have to give a presentation at work to people so they understand the different parts of a bicycle (its for the insurance business).
I need a powerpoint demonstration comprising a bike frame with all the various bits (wheels, transmission etc) that I can progressively build up into a complete illustration of a bike.
Before I go and develope one myself I wonder if anyone in bikforumsland has such a powerpoint slideshow or knows of one that I could use.

If I have to build one up myself, then it would be great if I could use high quality, simple illustrations of bike components. Again, do you know of a source ?

I am a complete powerpoint newbie so I don't know about suitable image formats yet.

Thanks
MichaelW
