Way back in 2020 when bike parts were super hard to get we panic bought a bunch of 10/11 speed stuff just to make sure we had something to put on bikes. We built a couple bikes around them, but mostly they just sat around taking up space, and now it's time to move it all out. 

These are the 11 speed cassettes ranging from Deore to XT. Not something we use often, but they're nice. They all work well, so just pick the cassette based on the gearing you need.
