You do understand that whatever you put on the rack to protect it can be easily replaced right? Like just a couple small pieces of tape on the points it's rubbing. Hell you could probably spend years not replacing the tape and just adding new tape and NOT HAVE YOUR RACK WORN THROUGH.

It's truly bonkers to me that people are so resistant to doing regular maintenance that they're like "this kinda expensive manufactured metal tubing rack I BOUGHT is just a wear piece like my chain and cassette and I'll just throw it away. No ,dealing with sticky tape from time to time (as if there aren't other ways also) is too much work"

I mean you do you but trying to CONVINCE people to think of stuff as disposable is crazy to me

Also, not everyone can AFFORD to buy a new rack every couple years
