Could we get a section dedicated to discussing/reviewing gear? I know this section would have good flow.

Heres a start:

Going down 1 tooth in the front will give less top speed and more torque
Going up 1 tooth in the front will give you less torque and more top speed
Changing the front sprocket 1 tooth is the same as changing the rear sprocket 2.5 teeth
Bigger diameter tires will creates more top speed, stretches your gear ratio and will require less gear changes

Smaller diameter tires creates more torque, shortens your gear ratio and will require more gear changes
