Putting boot to ass since 1967!
Next to the beautiful levers your linkage looks a little unrefined but STOUT(!).....
I was perusing the thread and I think your adjustable clamp to the frame arm bit is a good idea and you've made the clamp base large enough to hold well without concentrating force on a tiny footprint.
It'd be nothing to do them for any size tubing or just have a reference mark cut and the end user could have them machined to suit maybe. As well, the adjustable arm angle is the shit! Give a couple options for length and you'd be able to cover a large portion of buyer's needs.
