Work fine, just a bit noisy.functionality, plus they look good with sealed bearings ,so far so goodFit perfectly. Nice quality. Smooth running.The 13t wheels seemed to fit my Deore 5100 good. Bearings seem ok but we will see how long they last. Might be a little more noise just from being aluminum, but my factory wheels were also aluminum anyways.If you need a replacement they should work but stock deore are probably better "less wobble" if they are still good.I bought em just for a splash of red lol - I'll hold onto my stocks incase they go bad.Function and look are 10/10 but the grit and grim of real mtb riding make these things a little loud. If you are like me and spend money on reducing sound, the gritty sound these wheels produce after a sesh will make your OCD meter redline
