Why Some VPP Suspension Bikes Feel Harsh — And How to Fix It

If you ride a bike with a VPP (Virtual Pivot Point) suspension layout and have ever thought, “Why does this feel harsher than expected?” — you’re not alone. VPP systems, popularised by brands like Santa Cruz and Intense, are known for their efficient pedaling and traction in a variety of conditions. But for some riders, especially those new to the platform or switching from more linear suspension designs, VPP layouts can feel firm or even harsh on rough terrain. As someone who has owned a Hightower LT, Megatower V1 and now a Megatower V2, I've battled with the harsh feel of a VPP linkage plenty.

In this article we explore why this happens — and how to make your VPP bike feel smoother and more compliant without sacrificing its signature performance.

 

 

What is making my VPP bike feel so harsh?

Assuming your bike and suspension has been set up and serviced properly (ie. suspension pivot bearings replaced, fork and shock serviced at regular intervals, wheel spokes are tensioned correctly and tyre pressure is set) below are 5 more things to consider when setting up a VPP bike. If you have not worked through the above, DO THAT FIRST. Then return and try the below steps.

1. Progressive Leverage Curve

Most VPP bikes are designed with a progressive leverage curve — meaning they start off supple or “soft” at the start of the stroke but ramp up in stiffness deeper into the travel. This helps prevent bottom-out and helps give the bike a poppy, responsive feel. The problem with this design is if your suspension setup isn’t dialed, this progression can make the rear end feel “stiff” or overly firm, especially on repeated square-edge hits.

The Fix:
On air shocks, consider removing some volume spacers if you’re not using all your travel. This will make the progression less aggressive and give you a more linear feel. On newer model Santa Cruz bikes, consider switching to a longer shock stroke to increase travel and give yourself more room to run lower shock pressure or less volume spacers. For example, on a Megatower V2 the shock stroke can be changed from 62.5mm to 65mm, bumping rear travel from 165mm to 170mm. This is a simple task and can be done while your shock is being serviced.

 

 

2. Too Much Low-Speed Compression Damping

VPP bikes benefit from supportive damping, but overdoing it — especially on low-speed compression — can cause the shock to resist movement over small bumps, leading to a stiff and chattery ride.

The Fix:
Dial back the low-speed compression a few clicks. If your shock doesn’t allow for external adjustments, consider a custom tune from a suspension specialist that softens the baseline compression damping.

 

 

3. Suspension Setup Errors

Because of the unique kinematics of VPP bikes, standard sag settings may not always yield optimal results. Running too little sag or too high pressure can make the rear suspension ride too high in its stroke, reducing sensitivity.

The Fix:
 Experiment with 28–33% sag (slightly more than you might run on a DW-link or Horst Link bike). Make sure your shock is calibrated for your weight, riding style, and terrain.

 

 

4. Inappropriate Shock Choice

Not all shocks are created equal. VPP bikes often pair best with shocks that offer strong mid-stroke support without excessive initial compression.  For most applications VPP bikes are better suited to an air shock which can be adjusted to provide good small bump sensitivity but retain bottom out resistance. Some OEM shock specs are chosen for climbing efficiency but may limit downhill comfort.

The Fix:
 Consider switching to a more sensitive shock like the RockShox Super Deluxe Ultimate or Fox Float X2, which offer more adjustability and better small-bump compliance.

 

 

5. Rider Expectations and Terrain

VPP bikes tend to reward active, aggressive riding styles. Riders coming from more plush or linear bikes may perceive the increased rider feedback as “harsh,” especially on slower, more technical trails.

The Fix:
 Adjust your riding style slightly — VPP bikes come alive when pumped through terrain and pushed into corners. Also, tire pressure, inserts, and even frame material (carbon vs alluminum) can impact harshness perception.

 

 

Here’s a graph showing Leverage Curve Comparisons that help explain why some VPP suspension bikes can feel harsh when compared to a DW link setup.

  • Progressive leverage curves (common in VPP designs) start high and taper off, which can feel firm at the end of travel.

  • Linear curves maintain the same feel throughout the stroke.

  • Regressive curves (less common) can feel plush but may bottom out more easily.


 

 

Final Thoughts

VPP suspension isn’t inherently harsh — but it does have a distinct feel that may require a more nuanced setup. When tuned properly, VPP bikes can offer an ideal balance of pedaling efficiency, support, and descending confidence. If your ride feels punishing, take a step back, revisit your suspension setup, and don’t hesitate to consult a suspension tuning expert. The right tweaks can completely transform your experience on the trail.
