so its been many years since ive had to acquire new hubs (thanks hadley and i9) but for my next build i will be getting something new, i've always been intrigued by the sprag roller clutch bearings. I'm aware of a few brands that make them, Onyx, Box (they purchased True Precision didn't they?). Who uses what? pros/cons? how do they compare to other high engagement hubs like i9 hydra?
