Review on 🔧 Slip Chuck by LEZYNE by Eric Temple

The black plastic speed chuck that came with my Lezyne Classic pump kept falling apart along the threads and would not hold up. I bought a sliding chuck as a replacement. It fits well on valve stems but needs to be held in place for a long time and slides. And yet you have to keep it absolutely straight or it will leak. I have since bought another speed chuck (new with threads intact) to replace the slip chuck. I was looking for something better than the Silca 90° cartridge. for disc wheels where a flat chuck is needed to fit in a cavity. The Silca is still the best (so far) but I have to hold the Silca with one hand and operate the floor pump with the other.
