What's the longest carbon or alu. stem that's out there?

[54ny77]

Am looking to get something in a 160+ to use as a fixed stoker stem on a tandem. Rise not important, I can solve for that. Curious if anyone knows of a quality brand that make 'em that long (besides Da Vinci custom ti tandem stems).

Thanks for any tips.

Curious as to why it has to be carbon or aluminum?

In any case, special stoker stems tend to be longer than normal stems, and there are even adjustable stoker stems, such as this aluminum stem from Zoom that can extend from 155mm to 200mm:

Or this one from ControlTech that can extend from 190mm to 230mm:

Yep I already have an adjustable stoker stem. They're tanks. Once fit dialed I want to go fixed length, lighten the load. Ounces saved ounced earned....

Look for trials bike stems. I got one for my tandem, 175mm I think. Brand was Jitsie.

Also keep in mind they have shallower angles than the adjustable stems, so assuming it fits in the right place on the seatpost you may need a shorter stem.

Thank you!

I was poking around the web and came across this site, tons of variability in custom ti stem.

I follow their (Weis) Instagram, but those welds look pretty horrible to post on a website imo. Maybe I got used to Bingham, Firefly, Moots, Mosaic beads? Tandems East has all kinds of stems. When I was shopping for one for my triple, I remember them having control tech aluminum ones. They don't have everything online, so a message or call would probably be better.
