Help IDing ti stem

[Robbos]

Anyone recognise the brand of this stem? Few details from seller. Odd angle for fork clamp, could be awkward with aheadset.

ibis

I believe you, but I cannot find any images online of one if I search for Ibis titanium stem! They all seem to have round tubing.

Interesting.

Is the upper part of the clamping tube original like that? Looks almost like its not square where it meets the top cap.
Thats most likely a 6/4 ti stem

cinelli grammo maybe?

Until proof otherwise, I suspect it is something no-name Russian or Chinese.

Very well could be. I would be very very careful when it comes to titanium stems.

Exactly! That's why I was seeing if it was from a reputable manufacturer before purchasing it. I like my teeth intact.

I would be surprised if it's US made or any big brand name. But it does look like a prototype I saw from Suburban Machinery in Ohio back in the 90's. They never put them into production. They just made seatposts instead. Post a link to the sale. Curious about it.

Looks like a Russian ti stem to me. Half decent, just make sure the edges aren't too terribly sharp on the steerer clamp.

I have no idea how some are ascribing any nationality to that thing, but in any case my question would be: why consider buying it at all? There are plenty of better designed, better looking ti stems from reputable producers out there.

You would need an angled top cap to use it.
No idea if anybody makes that these days.
Syncros used to make some stems like that.

I don't see any problem with getting that stem to pre-load the headset bearings properly using a standard top cap.
I would use a cap with a flat underside, which is my usual preference so as to minimize the amount that the steer tube needs to be trimmed.
Once centered above the steer tube, the slightly-tilted top cap will push the stem down on the steer tube while the clamp centers itself perfectly on the steer tube. In other words, the stem clamp really can't tilt on the steer tube at all once there is some tension in the clamping bolt, and a fine-tuning of spacers or steer tube cutting will leave the top cap nearly flat with the end of the steer tube.
The bottom of the stem clamp is still perpendicular to it's bore, so the headset won't know the difference.
This stem's design looks like an attempt at absolute minimalism, which only makes me more curious as to who made it.
