You're welcome. I am a Neos nerd. The Neos is a 'high normal' in that if the cable or shift selector breaks, the mech jumps to the largest sproggit to get you home, so that is where we start.

Tensioning the cable moves it to the second largest, the reverse of 'ordinary' mechs.

Once the tension is correct for the first to second distance, it is correct for all the rest but may need final twiddling at the other end of the sprocket range.

Neos mechs are a superb design and sit under the chainstay to avoid damage. When folding, the trick is to have the mech on the largest sprocket as you stop the bike, the mech is then fully retracted under the frame.

What perfection!
