“ Theres a guy on YouTube – Trail POV – who does kinematic analysis and his conclusion that was that there wasn’t anything particularly special about VPP compared to other suspension types.”
I’d agree with that. What WAS special is that VPP and DW-link were the first mainstream designs to get decent anti-squat and linkage progression numbers.
When I was looking at getting my first full-sus back in 2013 I was amazed at how many designs had regressive linkages and low (bobby) anti-squat. Banshee’s 2013 Spitfire looks like it had kinematics from the future, and the current version has changed little but so many other bikes now are like it.
And I think modern air shocks with good spring curves and proper damping have massively improved the situation so even simple single pivots can work well.
