If ane bicycle'southward caster is more positive than the other, the wheel will force the vehicle to pull in that wheel's direction.

Toe

Toe measures the direction that the wheels are rolling. It is imperative that a vehicle's wheels all roll in the aforementioned direction at the same fourth dimension.

By Number
