THE HELIX DIFFERENCE

Engineered for Mountain Biking — and Nothing Else

Most coil springs are adapted from other industries.
Helix is designed from the ground up for MTB.

Every spring is:

  • Manufactured to within ±2% spring rate tolerance
  • Constructed from a proprietary high-performance alloy
  • Tuned for fast response, long stroke, and low bind

Whether you’re railing berms, smashing tech, or floating loam — Helix gives you control you can count on.

WHY ±2% MATTERS

Spring Rate Accuracy = Predictable Performance

A 500 lb spring that’s actually 445? That’s a different ride.
At Helix, every spring is tested and verified to land within 2% of its labeled rate.

That means:

  • Your sag is accurate
  • Your setup is repeatable
  • Your bike feels consistent every ride

No guesswork. No variability. Just dialed performance.


MADE IN BC. READY FOR ANYWHERE.

From Nelson’s Loam to the World

We live and ride in British Columbia — home to some of the world’s most demanding trails.
Helix was born in the dirt here, and built to handle everything the terrain throws at it.

From technical singletrack and wet roots to high-speed park laps and backcountry epics, Helix springs are tested in real conditions, by riders who know what performance feels like.

This isn’t hype. This is Helix.
