Replacement bearings for the Mission Engage cassette hub, sold as a pair. Hub bearings cop a fair bit of weather and grit, so when they start feeling notchy or gritty it's worth swapping them out rather than putting up with the drag. Straightforward service part to get your rear wheel spinning freely again, and handy to have sitting in the toolbox before you need them.
