Building small wheels is the one time I’ll use straight guage spokes as even butted are difficult enough to find in the sizes for 20” or smaller wheels.
I’m not saying they don’t exist but would likely be Brompton specific so it could be a case of there’s one or two brands that do them that short.
They do. I built up a pair of Brompton wheels with Sapim CX-Ray spokes. They were a bugger to source though, and the spokes on the rear wheel proved to be snaptastically unreliable.
You’ll be lucky.
