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 definitely we understood we got the mech.

Fully cnc about 7075 and fully added, mean 3D printed about PA12. Any part replaceable as spare and really widely compatible.

You can drive it with Campagnolo 12 speed and Campy EKAR in 12 speed or with Ratio Technology upgrade kit for 10 or 11 speed mechanical SRAM shifters. You can drive with it, a wide range of 12 cassettes, just choosing the right length of cage
