> [@ertyui](#): > > I was thinking, would the seat holder work without the pin? What if I just forget to put it in, and tighten the clamps down really hard? No, please don’t do that! The pin is an essential safety part - even if Ming themselves do not know exactly why. You can check that below: > [@Ming cycle support](#): > > Yes, the top and bottom Q/R lever clamps MUST transfer the FULL weight force of the rider to the frame. The pin is to fix the seat moulding and avoid it to move down & around. We tried to use the QR seat moulding without pin in the beginning, but it moves down somehow." Please?? 😮😆😒 [Ming Cycle’s reply to ST-QRS-001/saddle bolt request](https://www.stridaforum.com/t/ming-cycles-reply-to-st-qrs-001-saddle-bolt-request/573/1) …also, you get an impression of Ming cycle’s support quality here…nowadays, 10 (ten!) years later it is still on that level… Edit: To be honest, it is much worse…at least for me. I’m waiting for a reply to my last request since…well…perhaps 18 months or so… ![](http://www.peppiclip.de/Smilies/assets/images/ab9.gif) --- _[View the full topic](https://www.stridaforum.com/t/that-silver-thorn-which-holds-the-seat-holder/1320)._
