We are mocking up the mechanism for the left-side handshifter to test how it works before we make the final parts. There will be a push-pull rod parallel to the front downtube, then behind the neck there will be a pivot point transferring the movement to the left side of the bike. Where I normally would do this in CAD first, this time we are making it up as we go along. I just make little sketches with pen and paper to explain to Aad and will put it in CAD later


For the pivot point itself we decided to make the final part without a mockup, as this will be welded to the frame and I already knew how I wanted this part to look. The pivot will have bronze bushings and a grease nipple for lubrication.
