I recently did a teardown of the suspension pivots on my '20 Giant Reign (see upthread) and was pleasantly surprised. Frame alignment was really good and the bearings were in good shape after 3 seasons. Two were running slightly rough so I replaced them but once they came out, the old bearings were actually smooth so apparently they were getting squeezed a bit. The replacement Enduro Max bearings are smooth even when pressed in. Possibly the original bearings being slightly too large in diameter?
Older iterations of the Reign like my 2015 27.5 had a flexy 2-piece aluminum upper link that made the bearings in that link wear prematurely. I tried cheap CRC no-name brand bearings in that frame and they lasted only 6 months or so. I then went for Enduro Max and they lasted a couple of seasons. The newer generations Reigns have a 1-piece carbon upper link that is much stiffer and fixes the problem.
I ride my bike summer and winter and don't hold back hosing it off after muddy rides (never with a pressure hose though). In my experience premature bearing wear almost always happens as a result of poor design and/or poor manufacturing, with too much flex, misalignment, or a too-tight or too-loose bearing press-fit putting more strain on the bearings than what they are designed for.
I agree SC's design is really neat but I also feel like they somewhat over-engineered it, probably in a reaction to their 1st gen VPP trauma.
