The custom stem thread

Made a high riser stem as well . Used a unicrown fork blade ( that I messed up)

And a regular 7• stem

Quite standard of a stem. Brazed in the top cap, made out of two washers and a short section of tubing. Welded the nut onto the bottom wedge as well. The bar clamp is tig welded, then fillet brazed over that because I trust my welding more than my brazing. Luckily, I found a set of 26.0 bars in my parts bin, though I was looking for an excuse to build a 1" quill with a 31.8 clamp.

Hello there.

For now I made only two stems but I have to make more. I use 1.5mm wall thichness tubing for pivot and bars clamps wich I think is okay. If it helps it is 35x32mm for bar clamp and 32x1,84mm I turn down to 28,6id for steerer clamp. All 25cd4s from ulm techno. I have some 28x0.9mm tubing for the body. Is it good for you or should I go for 1.4mm wall wich is the second option from ulm techno ?

Plus what do you think about steel frame and carbon fork (with carbon steerer ofc).
I’m thinking about building a bike with the allygn mud fork.

Thanks !
