I’m another underwhelmed Park PCS 9 owner. I only paid £54.99 for mine brand new from CRC in some silly deal back in 2016 so overall quite happy with it for the price but here are my gripes;
1. The weight a bike pulls the stand forward a bit so the clamp isn’t completely horizontal. I rectified this a by installing some shims on the legs but its still a slight annoyance.
2. As others have noted above, the clamp head binds when tightened and refuses to rotate unless there is a bike attached. This is annoying because if I am working on two bikes, one of which I want to secure using the top tube, I’ll have to attach it via the seatpost first to get the leverage to unbind the clamp in order to rotate it so I can attach via the top tube.
3. I’ve never really had an issue with portability / storage because I leave it up all the time in the corner of our dining room. However, without the quick release clamps of the 10, you need to collapse it using a hex key and even then, you’ll need some sort of rope or strap to hold it all together.
There’s no way I’d buy one at the cost they are now!
