The other down side I see on this is the single pivot point swing arm. The chain stays are not linked through an a-arm or some type of dual articulation pivot, so I imagine bobbing under load is gonna suck and be exponentially worse if you squash it while on the gas. Specialized is trying to pass a similar setup off in a 140mm travel frame with a single pivot. I've ridden it and it sucks. The Trek Fuel (2018 and newer) is a 130mm single pivot... Also suffers although not as greatly. Also feels squishy and unnatural, especially after you've ridden a bike with linkage system like Yeti, Santa Cruz, Pivot, Niner, Transition, etc... Once you ever ride a managed arc rear travel system, especially if you have to climb, it becomes pretty obvious the benefits over single pivot point.
Like I said in the 2019 post. I hope these manufacturers start looking into mid and long travel linkage systems that manage the arc travel of the rear axle.
