Tucker, It’s not ‘Self adjusting’ really, its just that a lot of them seem to not have the locknuts properly tightened down from the factory. 🙂 But you’re doing the right thing. Sling some decent grease in ANY C&C hub, and adjust them properly from new and they lasts forever!
And as for cartridges being easier maintainance? Nahh, not really I defy anybody to replace 5 Pro 2 bearings quicker than I can service a C&C hub. Granted, I seem to have the nack for it, but it’s not hard as long as you have cone spanners: Adjust the cones until they’re a bit tight, lock the lock nuts down, then use the cone spanners, one on each side of the hub to slowly and gently back the tightened cones off until they’re smooth. Don’t keep loostening off the locknuts and trying to retighten them down with the cones ‘just right’, that’s like trying to bottle fog!
If I had a video camera, I’d stick it on You Tube to show how easy it is! 🙂
