You missed what I wrote, I've seen these damage the frame from being overtightened as well and honestly although I don't believe doing so would be a problem for me, I also can't be bothered to waste the money buying something I'd hardly ever use. Not when I need plenty of other tools before hand.

It wasn't till the frame arrived that I knew what post to get, do you keep every size post in your parts bin?

With any of these just learn how to be careful, in 16 years of working in a shop and 25 years of working on my own and friends bikes I've only ever damaged one frame in a stand, it was early on and it was my own. Good lesson, just learn to be careful with what you're doing.

With carbon fiber, you need to be careful with torquing anything that contacts the tubing. But at least there's no danger of damaging paint or decals when you don't clamp on a frame tube.

No. I have the predecessor to the ISC-4, the ISC-1. But I do have several posts in various diameters as well, and steel posts aren't all that expensive, especially if there's a co-op or used bike shop where you can pick them up really cheap.

Maybe wrap the clamp wit a rag or some of that pool noodle type foam bikes come packed in from Asia

and carefully set the bike frame on top of the repair stand foam pad it too..

no it wont be steady but you wont have to sit on the floor or turn the bike upside down...
