The first World Cup of the 2022 season is coming up and what better way to get excited about it than diving into the details of a World Cup level DH rig. Today, Christina Chappetta is in the studio with Jackson Goldstone to cover his all-new Santa Cruz V10 and what it's like being on the Santa Cruz Syndicate team.

Without putting words in the kid's mouth, what he's likely talking about is spring rate vs. speed. Going faster means you hit stuff harder, so you need stiffer springs to absorb bigger impacts. Remember, kinetic energy = 1/2 mass x velocity squared. So, on a modern WCDH track, you're going to need to increase spring rate compared to your slower local trails to get a comparable feel.
The underlying issue is something that completely stumps a lot of inexperienced suspension tuners. Without getting into the influence of leverage ratios and dampers, a setup that's 20% undersprung gives a lot of feedback (harshness), since you're functionally riding around with less travel and bottoming out more frequently. On the other hand, a setup that's 20% oversprung will give up traction, but can still be pretty comfortable/absorptive, especially on faster trails. People get this wrong ALL THE TIME, and go softer on springs and clickers, then get confused when their bike gets harsher. Hope that clarifies things a bit!
@DirtCrab: Ah cool! yea that actually make sense! I guess that is the type of thing that you learn from data acquisition and seeing where you are actually riding in your travel, and if its too deep, bumping up a spring rate. Obviously a mere, slightly overweight rider like me going half the speed of these boys isn't pushing into the bike as hard, but still probably good to think about, if you're riding deep in your travel constantly, you're giving up suspension performance and grip.

Not a single new / report / track walk / whatever from Lourdes DHWC 1st round on Pinkbike.

OK
I can honestly weep when I scroll down PB homepage and more than 50% of the “articles” start with “Video”.
