Awesome 1930′s era video explaining in detail how a differential gear on a car allows the wheels to turn at different speeds when going around a corner – if you don’t already know how it works (and I’ve got to admit that I didn’t) then I promise you that a light bulb will go off over your head when you see how simple and clever it is!

Next “limited slip differentials” – knowledge awaits!

Ha! Good point, well made.

The only problems being you have to know or find a place to padlock your bike, the weather (it’s winter in the AU atm – and its rained about 20 out of the last 21 days ), and I need to cart a minimum of two bags to school each day… Bah! Excuses, excuses.
