Compressionless brake cable outers are only for cable brakes. Basically they replace the standard coil construction, which is compressible, with a longitudinal wire construction, which, just like ALL gear cable outers, is not compressible.
The Shimano you are looking at are hydraulic brakes, so it does not apply
