Default Q: Shimano cantilever straddle cable length?

one?
Is it related to rim width, where we want length that produces a
specific angle based on brake model? Does that mean the geometry
won't be quite right when switching to another rim? I checked the
Sheldon stuff but don't have enough experience to pick the right one.

You want the size which ends with a 90-degree angle as the
pads touch. That varies by brake stud position and rim
width. Some brakes allow lateral pad adjustment which can
help to get that just right with various LinkWire sizes.


That's it. The brakes came with two different straddle cable sizes;
the previous owner worked at a shop and must have swapped in what
worked on his bike. That means I can try each and check the angle.

How are Shimano straddle/yoke cables measured? Is it base on the
length that sticks out of the middle?

Thanks!
