The main problem was that I have a Velobuild frame, but the integrated handlebar with the shortest stem was too long. So I bought a Kosevlobike handlebar with a shorter stem. Since the shape of the velobuild frame is not the same as the Kosevlobike handlebar, I designed a part to make this transition.

After several months dailing in my position on the indoor trainer, I got the correct spacer height. For me it was 45cm. Quite high, but I am not as athletic as I want to be. Since I don't think I will change the height anymore, I didn't design a 2 piece part. I believe this might decrease the rigidity and the impact strength.

For the materials, i used PETG.
I had bought a spool of carbon fiber enforced PETG, but I have read that the carbon fiber envorced PETG has a lower impact strenght in the Z-Axis ( https://blog.bambulab.com/bambu-carbon-fiber-filaments/ ). And for as far as i think, this Z-Axis impact strength is the most important one. I live in Flanders, and the roads and cobbles give quite some battering, which translates to impact on the Z-Axis.
And, since the impact on the Z-Axis is on compression, I don't think that layer-adhesion is a big issue.
For the creep, I have left some milimeters to retighten afterwards. If I have to tighten to frequent, I will change the material or reprint.

I used a 100% infill

I have ridden it now only for 60km. Including a downhill cobblestone section. The spacers held well.

If the spacers don't hold, I will update my findings here. So, unless if I had a very catastrophic failure, when there is no repost, the PETG spacer is holding on.

Let me pick this old Topic. Any more experiences?
I am encountering a similar issue (3rd party handlebar on my new SL9 and another one for m Cube Gravelbike).
I scanned the transition spacer from the SL9 and QuickPro handlebar and designed an own version.

Since basically my life will depend on this spacer I am very interested in first hand experiences.
Id be printing PET-HF. Was recommended by Gemini and Claude for load bearing on my H2C. 0,6 nozzle and 100% solid (or 0,8?)

The green is YS 3082-1 and the white is YS 894-5, which has a nice anodised look to it. Doesn't really show in the photos. Pleased with both.

Just a note for those ordering riser bars - the foremost hole/threaded insert for the computer mount is on the curve of the bar, so a completely flat computer mount won't fit (unless you want your bolt inserting at an angle...). I'm told the XMCS ones are curved to fit.

Care to share more pics? Would love to see the complete bike from normal angles

Does anyone have pictures of the 2 color choices:

Pink & Blue Chameleon white and Pale blue purple chameleon?

Yeah I get your point, but he is rinsing a Canyon Road lite on the trainer currently which has about 0-2cm between saddle and handlebar so he is kinda used to a more sporty version. I don't think he'll like going up with a MTB. This would look like shit (btw: currently he sits at 2.3W/kg FTP, rode up Alpe on Rouvy Multiple times - but that's not the topic here )

He guys, I want to build my dad a cheap gravel/road bike. He never had one and just turned 76 - his dream is one day being able to ride AlpDHuez. That's wh I want to build him the right tool for this.
I think he'll need something in the Area of 46-51, so having a small reduction overall would be nice.

I heard lots of the Atwood but there are a gazillion versions on AliExpress- can anyone pinpoint me in the right direction for it? I'd guess leaving any front derailleur and problems will be easier overall...so 1x12? 1x11 should do it?

Hey guys,

thinking of pulling the trigger on 2 bikes. One is for my girlfriend - she has a 2019 Cube Sting WS (120mm overall travel) and uses it for light trails (S2 max) and some blue lines in bikeparks (She doenst jump). Would you say the 936 suits her?! (She is 162cm with inner leg length of 76cm - Id suggest she takes an S?)
What budget-solid choice would you recomment for shocks?

Last thing: Are there any pics of the chameleon style colors?! Saw some in a german forum as samples on a tube and want to see them for real...

Thanks
