Question about Gessi Rettangolo single-lever basin mixer, without pop-up waste, 129 mm projection, 20002

Unfortunately, we are currently unable to offer a replacement cartridge for the Rettangolo single-lever mixer 20001, please contact the manufacturer directly: https://www.gessi.com/de....

According to my research, the Gessi cartridge SP01411 with a diameter of 25 mm is suitable for this model. This cartridge is also used for other models in the Rettangolo series.
