Thanks for the feedback! I disabled the text animation for the time being.

There is a note about the star nut if you click on the headset top cap and then explode the headset, and I also mentioned QR vs thru axle briefly when talking about the fork. BB is definitely missing and I should add it. I was also thinking it would be fun to make the wheel explodable too, which would give me a place to talk more about hubs, spokes, rim standards, etc.
