In response to a question from Paul Raley, I've tried to measure the reach of the Universal side-pulls in my box. I find three different flavors, with approximate measurements:
short long embossing or model name ~49 ~63 Universal (l), Super 68 (r), ~ 1.7 cm arm below the 68.
~55 ~66 same as above, but ~ 2.5 cm below the 68.
~57 ~75 Universal Extra (left side)
If someone wanted to provide a home for such absolute essential trivial data, welcome to include this, and I can send data on relative leverage of a bunch of vintage brake levers, too.
