Ratio Adjustment Function

Adjust the lever pivot to the action point in 0.25mm increments (up to 2mm) to change lever touch. Increasing the ratio results in a shorter, firmer stroke, while decreasing it results in a longer, softer stroke.

Example: Ratio Adjustment 16-18mm


Pivot-Action Point 16mm
Stroke: Longer
Lever Touch: Softer
 
Pivot-Action Point 17mm
Stroke: Standard
Lever Touch: Standard
 
Pivot-Action Point 18mm
Stroke: Shorter
Lever Touch: Firmer
