Derailleur cages and OSPW systems
If you've fitted an aftermarket cage or an oversized pulley wheel system, it now has a home of its own. "Derailleur Cage / OSPW" sits in the Groupset list when you add a component, right below Front and Rear Derailleur.
It arrives with a sensible default life and a built-in reminder to check the pulley wheels and bearings, since those are what wear out long before the cage itself does. Both are yours to change — set your own distance, or turn the reminder off entirely.
Wear predictions cover it too, so as you log rides your estimate adjusts to how and where you actually ride: wet weather and gritty roads shorten a pulley bearing's life.
