Comes with pre-set gear meshing and initial angle (15 deg, front side). Angle can be changed before putting this setup on the deck, (3 total positions).
Angle adjustment is not threadlocked. It is not necessary, but recommended to use a bit of threadlocker after setting up wanted angle.

Every other drive train screw is initially threadlocked.

All bearings are pressed in using a thermal press method, not press-fit, especially not foot press-fit.
All bearings are pressed into Aluminium.


Bearing differences:

  • Straight cut gear drives use groove ball bearings.
  • Helical gear drives use angular contact ball bearings to sustain the axial loads.


Gear types and materials:

  • Wheel gear is machined from plastic (harder than POM, equivalent to aluminium hardness).
  • Wheel adapter is aluminium.
  • For straight-cut gears: motor gear is aluminium.
  • For helical gears: motor gear is steel.


The kit comes with custom CNC machined wheel hubs with a negative offset to make them fit on normal longboard trucks. Other wheel hubs do not work as these also have a special mounting plate which reduces total width of the drivetrain.
