When I stripped this down to do the 200hr service on the shock is when I found this. All bearings appeared fine so far as I could tell. I didn't see anything out of the ordinary when checking it. Is there anything in particular I should look for when checking the bearings? They were all seated appropriately, no sticky points, nothing grimy... etc. The swingarm mounts appropriately as well, once again, so far as I could tell.

Hi guys, I wanted to know if the bike easily accepts the entire 165 * 42'5 shock travel. I ask this because there are bicycles that, although they accept 115mm of travel, it is very difficult to get them to give the full travel. I don't know if I explain myself well, since my native language is not English.

Max. pressure for DT535 is 333 psi. So yes, 300 is quite a lot. But i used about 75% travel on my first ride, wich was pretty careful because of the slippery ground. When i gain some confidence and ride harder, there is not much room for lower pressure.
I started with 25 % sag on the first checkout ride. That was way too bouncy for me, felt like using 50% travel when riding an even asphalt road.
Rebound is at 11 from 22 clicks.

I ordered it from Carbonda - like $15 shipped.  Mainly ordered it because I was afraid I was gonna strip my bolt head out as well trying to get it tight enough, mine would spin too when tightened to almost the point of stripping.  I could feel the movement in the pivot still if I squeezed the non-drive crank arm against the chainstay and put my finger on the pivot.  Once I shortened that pivot pin like Adam suggested it fully tightened with ease and didn't spin and most importantly didn't creak anymore.

That was what I had as well, about 83mm.  Filed mine down to almost 80mm I think and that did it for me.

Any 182cm/6' folks on large frames, what size dropper have you installed?

Go with the 40. 42.5 gets nothing more than a risk to the warranty. I wonder if the cracks referenced to the rear triangle are due to running a 42.5.

You are running both 120 and 42.5 right? Any Idea on how much sag you run? The difference to pedal striker may either be running to much sag or you running 100 and 40MM

Just a heads up for those interes

I was really hoping for a 909DC rather than 936DC, as the dirt is so fine and so much of it here, that it's like riding powdery snow on some trails.  I've decided high horizontal rear shock mount is definitely the way to go.
