Two of my bikes have Alligator iLink housing on them. If your bike has mechanical brakes, it’ll be about $100 per bike for the setup. It’s basically aluminum beads with a liner inside. Absolutely no room for cable compression or wires bursting out the ends. Replacement is just adding a new plastic liner and cable.

Jagwire makes a similar product but it has a section of regular cable to go under the wraps, so that could become an issue over time.

Is it better? Not when new. The idea is that it never gets much worse over the years.
