Stem Clamp Diameter for this Salsa Stem?

Hey all. Looking for info on this Salsa stem, specifically stem clamp diameter. The guy who sold it to me says he thinks it's 26.0, but I can't find any markings to indicate if that's true. Anyone know for certain? Thanks!

That hole doesn't even look round any more. I don't know how you would safely mount any handlebar in that, unless its some kind of optical illusion in the picture.

I'd expect it to be 25.4. An MTB stem that's several years old? Road stem that age, maybe 26.0.

I would normally suggest measuring the inside of the clamp, but I suspect with that stem you'd get 26.5 in one direction and 23.1 in another.

I wouldn't use that stem if I had any other option. The damage to the clamp is significant.

Yeah there's definitely no damage to the stem at all. It's just the angle of the picture hahaha. Don't worry. But if you have any product information or anything of that nature that would be really helpful.

Definitely an illusion!

There's a lot of old Salsa stems floating around with a 26.0 clamp, and this one might be for dirt drops. Definitely by an MTB brand but is it an MTB stem? I cannot say for sure! Hoping someone has catalog info or something of the sort!

Angle of the photo ?, BS. The stem looks deformed from over tightening of the bolt. It's aluminum and that can happen. I'd not be using that stem as it might crack just above the bolt on the face. I've seen stems fail that way, especially well used 1" single bolt stems. Rider goes endo when that happens.

Are you sure it's aluminum? The weld looks more like a steel weld to me.

IIRC its not a parallel surface; it has an angled cut on either side, similar to this

If you don’t have calipers to measure it, just try to put some bars of known diameter in there. The chance of someone here coming up with a reliable definitive answer is slim.

Take a piece of paper about 100mm x 40mm. roll it up around the long dimension. Put it in the stem and push the paper inside the stem with your finger to unroll the paper, tight against the outside of the stem. Make a pen mark where the edge of the paper is. Unroll the paper, and measure from the edge to the mark. Divide by 3.142. Should have the diameter or thereabouts.

Hahaha why are you so aggro about someone else's stem? It's in my hands right now. I can guarantee you it's not deformed. I wasn't asking "is my stem deformed or not?" I'm asking if anyone knows what the stem clamp diameter is.

I know it's a long shot but I was hoping it'd be a popular model or something haha

That is similar to how it looks from the front. Certainly not deformed...

I'll give this a go if I can't find anything else! Thanks!

You are absolutely correct, an uncalled for attitude on my part. Apologies and as others have picked up on, the photo doesn't show the whole story and it also might be steel.
