Thanks for starting.

I've been meaning to start tracking shifter cable pull ratios. Most of it is online, but I wanted to verify the data myself. I'll try to build a rig to do it shortly.

Here is Sheldon Brown's Cable Pull Device.

One of the issues with road levers is setting up a standard mount. Less of an issue with MTB levers.

It would also be good to convert cable pull to brake caliper movement.
