I must be dense. I mean, it's like a pebble, a stone, and a brick. You through the pebble, it might hurt someone. Take a stone and throw it, it's gonna leave a mark. But a brick, that's going to be brain damage.
So, you could take physics into it, and explain the whole thing about mass and velocity, and impact and transfer of energy.
But, really. If you need a pebble, you use a pebble. If you need a brick, you use a brick.
Seems like people work to hard to caculate what they are doing and.. don't really enjoy what they are doing.
Or maybe it's a hobby.
I just don't get it. Must be something wrong with me.
But let's say that you ride a bike geared at 48x16. Someone rolls up with a bike geared at 48x16. Are you pushing the same gear? If the person's wheels are a different diameter than no, your gearing is different. And what about that guy riding 39x13? Is it immediately obvious that he's riding the same gearing, assuming that you both have the same size wheels/tires?
Gear inches make comparisons easier. Instead of saying "I ride a 47x16 with 700x23C tires" I can say "I ride 77 gear inches." You tell me which is easier.
