Always attentive to the needs and problems of the operators in the sector, PMS has packaged this very practical square for all those who frequent the tracks and who always need to make new adjustments to the suspension and to the geometry of the bike.
This particular tool made of steel precisely in order not to allow deformations on the measuring axis allows you to have a fixed reference point from which to measure the height of the rear without margin of error and thus restoring all the characteristics prior to the modifications.
The system must be "calibrated" at the first installation to allow an ideal coupling with the fixing points to the frame, and from that moment on, all the measurements made from the wheel pin to the preset reference point can be taken without errors in order to to be able to create a history or a valid starting point from which to make adjustments, being able to quantify them through a linear measurement that is always comparable even after having disassembled and assembled the shock absorber (in this regard, look at the practical shock absorber jack by PMS).
The bracket is supplied ready for use and with all the bushings and thicknesses necessary for assembly.
