Pro Truing Stand
Material: special tool steel 
The calipers enable simultaneous radial control of the wheel position on both sides, with an  additional possibility to control radial symmetry in relation to the hub. 
The geometry of the calipers enables a simultaneous axial control for accurate truing of the rim. The calipers have plastic coated tips to prevent scratching the rim. 
The upright arms position can be adjusted with an upright adjustment knob to fit the axle  width. The caliper arm position can be adjusted to fit the wheel radius and the caliper tip  distance can be adjusted to fit the rim width. 
When changing the wheel, the spring loaded upright arms and the caliper arm can be quickly  pulled away, automatically springing back to a set position when inserting a new wheel. This  enables faster truing of several same size wheels. 
Accepts wheels from 16 to 29 inch with or without tire. 
Truing of 20 mm or other dimension axle wheels requires additional adapters. 
Truing control of brake rotors can be done with additional calipers inserted into slots in the  upright arm. 
1689 professional wheel centering stand arm can get out of center after being used frequently.  Controlling caliper arm enables us, to calibrate the stand arm back to its center position. 
Supports hubs up to 157 mm width. 
Additional holes are useful for storing all the three dimension hubs inserts 1689.3 (12, 15 and  20 mm). 
Additional nuts in the bottom part of the stand enable easy tightening to a workbench.
