The angle of the Steering Pivot should be around 63 degrees. Angles bigger than 70 deg. will make the bike nervous, whereas very shallow angles result in increased wheel flop and huge turning circles (This was the major drawback of former center-steered lowracers with positive trail).
The choice of pivot angle has following effects:
- it influences the amount the seat rise when the bike is turned self centering effect.
- with a low angle makes the tendency for Wheel Flop larger.
- with a large angle makes the tendency for Pedal/Steering Interference larger.
The influence on the seat rise can be calculated and is shown in following graph:
