This is an initial review written two weeks after installation.The bearings seem decent and run very smoothly, they arrived quickly in simple packaging but you don't need any more.I have installed these into the front hub of my mountain bike wheel where they seemed to be a perfect fit. As for the longevity, I cannot comment at this time but do run very nicely just now.So far I'd recommend.

I used these to replace the worn out bearings in a Hope Pro 2 Evo mountain bike hub. It was perfect for the job.

Inner race tolerance is wrong for 6903 2RS At least 0.5mm too small so axle cant fit through! Should have known bearings from Amazon would be rubbish. Buy cheap buy twice. Back to Enduro it is.

Replacement bearings for MTB rear wheel. Job done. Good value and quick delivery.

Quality product.
