The Pro-Ject 60g Counterweight is a genuine replacement counterweight designed for Pro-Ject tonearms using the 007 bearing housing, including the 9cc Evolution and other tonearms in the 9-inch family. Fitting the correct counterweight is essential for setting precise tracking force and anti-skate, ensuring your cartridge tracks the groove accurately and without damaging your records.
This 60g version is intended for use with heavier or low-compliance cartridges that require additional counterweight mass to bring the tonearm into balance. Pro-Ject counterweights are precision-machined from brass, providing a dense, compact mass that sits concentrically on the tonearm stub to minimise bearing side-load.
If you are unsure whether the 60g version is the correct choice for your cartridge, consult your cartridge specification sheet for its weight and compliance figures, and compare against the recommended counterweight range listed in your tonearm documentation.
