In my naivety I expected all outer cable to be non compressible to a large extent but on cabling up the Drypod2 it was clear that the lever was moving and the calliper wasn't once a certain pressure was achieved. This was using non branded cable outer from a 25m roll. I'd used a fair bit of this outer before without any real issue but here and now it was terrible. Whether old age had got it or I'd hit a badly made patch I do not know. A search online finds such an invention as non compressible outer as a separate and better thing to regular outer so I bought a couple of metres of Jagwire's version of it and what a difference. Doubtless some here know this already but it's new to me. No discernable compression at all and almost all my effort going into squeezing the pads rather than the outer. It was about £6 per metre off ebay. It's something I highly recommend over the regular stuff.
