Downtube/Stem Mount Friction Shifter to Brifter Adapter

Allows you to adapt friction shifters from vintage bikes to attach onto brake levers to create your own friction brifters, similar to Gevenalle brifters.

I created a youtube video that explains the installation and process of installing them: 

These were designed to be printed in TPU/TPE which has very strong layer adhesion. 64D or harder TPU/TPE is recommended.

You'll need tree supports.

I used these simple downtube cable stops since they had a very easy to print geometry: https://www.thingiverse.com/thing:5184346

But there are others out there that allow you to add an inline cable tension adjuster.

Changed the geometry to work better when printed in TPU, along with a model that works with stem mounted friction shifters.
