I ordered 1m of the generic brake cable from Ali. So, flexible I didn't use it cause I figured it would be spongy or blow the casing open. I found jagwire shifter cable in bulk at same price per meter about 3-4 months ago on Amazon. I bought jagwire lex-sl for shifters and more expensive keb-sl for brakes.
I have bought generic hydraulic hose from Amazon. I expect it to be the same as aliexpress. It was simple to cut and put fittings on. I haven't tried them yet but are on shimano 805 flat mount calipers.
