Road Cycling“It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway
Oh yeah, you mean the beaded stuff? It's a right bastard, especially if the beads aren't tight on the liner, and free to move along it... Alligator i-link is like that, and even worse, thanks to the little bulges on one end of each bead. Jagwire Elite Link is way easier.
Yokozuna Reaction housing. Super stiff stuff and the outer jacket isn’t completely smooth either. It didn’t help that the far edge of the handlebar channel where the housing exits was sorta thick (perhaps some clear coat build up or resin). I forced the housing through that tight spot on one side then got smart and opened up the other. Still a pain to feed through. Shift housing was a breeze in comparison. Regular housing or hydraulic lines would be similarly easy.
