Notes

  • It is advisable to make a preliminary run of the freewheel to eliminate excess grease from the mechanism and ensure the correct setting of the pawls. This process can be accelerated by introducing a little oil in the groove between the center of the freewheel and the teeth.
  • If the freewheel is used for Trial without having set the pawls first, it will not work properly and will cause it to jump, damaging the slot and the pawl.
