If you met someone at the trailhead, asked them what % progressive kinematic their frame had and what is the leverage ratio they would look at you like you were an alien holding a rectal probe. "I bought it because it was blue" would be their response. Normal people don't care about this stuff lol. I've tried them all over the years, from literally Regressive designs, through to 45% DH monsters. I keep coming back to 25% been my sweet spot on a coil for an enduro/long travel bike. It's my goldilocks number. What is more important, is the Ratio...
