Are these safe?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Are these safe?

I've been seeing a few of these lately and just wondered if they are at all safe. Just seems like an aweful lot of force for the two attachment points to take care of.

What do you mean by "these"? Pop-top stems in general?

They are the standard design for threadless stems, and generally lighter-weight than old-style stems. Also, they're much more convenient for removing or adjusting the handlebars!

If the clamp bolts are properly installed and torqued, they are safe.

All stems with removable faces i've seem have them in the front, not due South. Just couldn't see ever trusting this stem 100%.

removable faceplates are safe but the 3T Motus stem apparently is specifically known to have cracking problems

If the parts are well-made and installed properly, I suspect you'd destroy your bar before you'd manage to rip either of the two bolts out of the stem...

Assuming that the quality is decent and it's set up properly, you couldn't break that if you tried.

Sometimes people forget how strong metal is.

Any idea where to get some of those?

I could use a couple for a build.
