OneUp, WolfTooth, and Hope all have replacement alloy sprockets, though they're $90 or more. When I replace mine, I'm probably going to try something from ZTTO. They have an 11-speed 10-42 that's all steel, XD, 305g, and $170 or so. Lots of interesting alternatives [here](https://docs.google.com/spreadsheets/d/16C3Rz6qmzmurSNd-L3IeMSFukkBFV6D1DRbfS59EDrE/edit\#gid=1997587322 "here").
