1x12s ROAD/MTB REAR DERAILLEUR
 
Nothing new apart from everything
We started this project in 2017 and step by step we reached the target right now after 4 years, changing all the parts at least 10 time each. Thinking about electronics, about mech, about both. But definetly we understood we got the “mech”.
Fully cnc about 7075 and fully “added”, mean 3D printed about PA12. Any part replaceble as spare and really widely compatible.
You can drive it with 11s or 12s shifters for drop bar and flat bar, Campagnolo, Sram, Shimano and more. Enjoy it
