Default Q: Shimano cantilever straddle cable length?

somebody wrote:
I'm thinking of using some Shimano BR-550's on a road bike with Alex
DM-18 rims. I can pick one of several fixed straddle cables. Which
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.
