Trendy 1x MTB drivetrains with massive cassette spreads imply actually lengthy derailleur cages that get perilously as regards to the bottom, even on 29ers. Just about each present mountain motorbike derailleur I personal has scrapes on its cage across the decrease pulley. For the alloy cages, it’s most commonly beauty injury. However each gouge tells the tale of a derailleur cage that were given momentarily hung up on a rock, possibly a derailleur or hanger moderately bent, and was once moments clear of getting ripped off. Then, with carbon cages like on XTR (see beneath), every of the ones affects and scrapes dangers delaminating carbon fibers, that can in the end splinter and fail.

Call to mind it as a vintage low-friction MRP bash guard in your derailleur cage as a substitute of your chainring.
I don’t know the way many damaged derailleurs an 8g piece of MRP thermoplastic may save, nevertheless it’s most probably reasonably a couple of.
