The Satori has a cylindrical not the split style, a much better look than the Delta. The delta is split clamp.

At some level, anything except for a full split cylinder should, at least in theory, prevent even clamping pressure. Is it enough to cause harm in practice? I certainly cannot answer that.

I have, use, and enjoy a stem riser on one of my mountain bikes. It's a cheap no-name from Amazon and it's worked fine. It's on an aluminum steer tube, though, and I don't think there are generally any concerns with such a setup. I use it as a "soft roader" bike only, and don't subject the bar or stem or riser to any loads higher than what I'd consider "moderate" trail type riding.

Nobody here is being hostile or condescending. You have been told by a few people in this thread that you are wrong, yet you double down. As Kontact said, it is not OK to try and convince people that warnings on products should be ignored. That is whether it is bike stem extenders or ladders.

Love those Monte Cristo Whites.

The origin 8 stem I use looks a lot like the one you posted.

Listen to the warnings but ask questions. I learned a few things so worthwhile discussion. What I said about the leverage isn't wrong. High school math as some non-hostile person pointed out.

I think this thread has run its course, there is enough information here for people to make their own choice.

Have a nice day. Need to go adjust the headset on my stem extended bike, it needs a tweak after I replaced the front fork.

Learning is always good.

At the end of the day, it's not whether the odds are in your favor. It's what are the consequences of being wrong?

This type of clamp is never permissable on carbon steerers, even on stems.
