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 SRAM 1 by 11 speed dropbar triggers
