 Ooof, harsh full bottom-out at 0:57.

 nope just properly set up suspension.

 @EliasFritzen: I don’t know, it seems like the rear suspension (my main focus, as fork looked right for that hit) should be either more progressive or not immediately blow through the travel...he was bottoming out before his legs even bent to take the impact from just a 5-foot vertical drop to nice transition on a full enduro bike. In my experience racing DH at the pro level (and tuning suspension with some of the very best in moto and MTB), you’d want to either increase the high speed damping and also tweak the shim stack for that specific suspension design for these sort of hits without affecting small bump sensitivity, increase the end ramp (via linkage or air volume or by or bladder/piston charge), or possibly slightly increase the main shock air pressure if you’re regularly hitting stuff like that and bottoming in the rear. I’ve heard that those specific Pivot designs (that bike and their 2018ish Phoenix) can be harsh off the top on small bumps, braking bumps, choppy hardpack, etc (per the Phoenix redesign which specifically addresses that issue) and thus some people run these Pivot models a bit soft to compensate for it so they don’t lose traction when cornering on choppy terrain. But then again, maybe people like to blow through their travel...but every top rider I know goes through extensive tuning to limit this sort of bottom-out scenario by fine-tuning their high speed damping so they can get optimal traction and suspension performance without having to run excessive shock pressure (reducing small bump sensitivity) to prevent bottom-out on a 5-foot-tall drop with tranny.

 @EliasFritzen: Likewise, you can see him buckle-wobble a bit when landing off the same drop at 0:53. Suspension should be setup to prevent that...well, if you’re on an enduro bike and it’s a 5’ drop. XC bike I would understand. But he needs more high speed damping / shim stack re-stack if that’s the air pressure he needs to ride that bike at its fastest.

 @EliasFritzen: Guessing that due to the inherent lack of small bump sensitivity of that Pivot model, he backed off the high speed damping dial to provide supple suspension performance on small and chattery bumps. But then it’ll likely blow through travel on big hits — hence the need for a shim stack that allows for limited oil flow restriction / damping on small bumps, but then has a second layer of bigger shims (with a spacer shim between them and the smaller shims) that bend/blow-off to restrict high-speed / high-volume flow of damping oil on big hits.
