What is Mechanical Trail
Mechanical Trail refers to the length of the lever that, when combined with the contact patch, produces a self righting effect on the bicycle or motorcycle. The longer the lever, the more the is held true to the geometry of the cycle and influenced less by ground conditions.
What is Ground Trail
Ground Trail is makes reference to an imaginary line on the ground. It means nothing. The only geometry feature that runs along the ground on a bicycle or motorcycle is contact patch.
Only ignorant people make reference to ground trail. Sorry folks.
The Math
- Offset = Wheel Radius * SIN(90 - Head Angle) - Mechanical Trail
- Mechanical Trail = Wheel Radius * SIN(90 - Head Angle) - Offset
