How to Read Torflex Articulation Dimensions
A) How high do I set the fenders?
Look at the 0° drawing: The 1.49 is distance from center of spindle to top of bracket. The -.81 is how far arm moves above bracket for 'Full Load'.
1.49 +.81 / 2.30
  • To top bracket
  • From top bracket to 'Full Load'
  • Travel from 'No Load' to 'Full Load'
Fenders should be located 5.3" above tires when 'No Load' (2.3" + 3.00 DEX RECOMMENDED).
B) What is 'Shock Load'?
'Shock Load' -1.73 is how far arm travels above the top of bracket. The distance the arm moves from 'Full Load' to 'Shock Load' is the difference of .92.
1.73 -.81 / 0.92
  • Distance arm moves from 'Full Load' to 'Shock Load'
  • Full Load Dimension
  • Travel from 'Full Load' to 'Shock Load'
C) What do the + marks on the curved broken line represent?
This line tells us how far forward the tire moves at each of the load points. Using the 0° drawing again: Notice the 6.0 distance from center of spindle to center of inner bar. When the arm travels up to 'Full Load', the tire is moved forward .46". At 'Shock Load', the tire has moved forward .94".
D) When trailing arm starts at 22.5° or 45° down, the calculations are subtractions rather than addition.
Look at the 22.5° drawing.
03.79 -1.49 / 2.30
  • 'No Load' is 3.79 from top of bracket
  • 'Full Load' is 1.49 from top of bracket
  • Travel from 'No Load' to 'Full Load'
'Shock Load' is .45 below top of bracket, so the travel from 'Full Load' 3.79 to 'Shock Load' .45 is 3.34".
