CHALLENGE

TRACTION IS THE PROMISE THAT A FULL SUSPENSION DESIGN STRIVES TO DELIVER:
THE ABILITY OF TWO TOUCH POINTS (TIRES) TO MIRROR THE CONTOURS OF THE SURFACE THEY ROLL ON. TO ACHIEVE TRACTION IS TO DELIVER IT CONSTANTLY, UNDER ALL CIRCUMSTANCES, REGARDLESS OF SPEED, SIZE OF TERRAIN, INCLINE, DECLINE, ACCELERATION, OR DECELERATION. A DESIGN’S ABILITY TO INTERPRET THESE NUANCES IS ENCUMBERED BY THREE COMPETING FUNCTIONS:

1. DESCENDING, 2. BRAKING, AND 3. PEDALING.

BECAUSE THEY CAN BE OPPOSING FUNCTIONS, DESIGNS ARE INHERENTLY BIASED AND THEREFORE COMPROMISED, RESULTING IN: BRAKE JACK, PEDAL BOB, OR A HARSH DESCENDING EXPERIENCE. BY FOCUSING INDEPENDENTLY ON EACH FUNCTION WE ARE ABLE TO BETTER DESCRIBE AFS’S UNIQUE SOLUTION...

WE OFFER TWO DIFFERENT AFS SUSPENSION SETUPS.
SEE BELOW TO FIND OUT WHICH IS RIGHT FOR YOU.

1. DESCENDING

  • FLOATING REAR SHOCK: Minimizes binding friction for smoother ride
  • LONG ROCKER ARM: Direct force transfer = increased bump sensitivity.
  • 2.5 MM REAR AXLE PATH: Poppy, lively, true trail feel
  • PROGRESSIVE LEVERAGE RATIO: Small bump sensitivity with big hit support (See graph).

2. BRAKING

  • FLOATING BRAKE BRACKET: Decouples suspension and brake forces = no brake jack
  • LOW ANTI-RISE: Values below 100% result in braking traction in any riding position (See graph).

3. PEDALING

  • POWERFUL PEDALING PLATFORM: 140% anti-squat eliminates pedal bob while retaining bump sensitivity (See graph).
  • EXCEPTIONALLY STIFF LONG ROCKER ARM: Increased acceleration when pedaling

1. DESCENDING

  • 15MM REARWARD AXLE PATH: Smoother ride, better traction, less hang-up
  • LONG ROCKER ARM: Direct force transfer = increased bump sensitivity
  • STRAIGHT LINE PROGRESSIVITY: Small bump sensitivity with big hit support (See graph).

2. BRAKING

  • FLOATING BRAKE: Decouples suspension and brake forces = no brake jack
  • LOW ANTI-RISE: Values below 100% result in braking traction in any riding position (See graph).

3. PEDALING

  • POWERFUL PEDALING PLATFORM: 120% anti-squat eliminates pedal bob while retaining bump sensitivity (See graph).

WE DON’T BELIEVE
TRACTION IS A 2 OUT OF 3 PROBLEM SOLUTION.
THE AFS IS A FULLY REALIZED, THREE PART SOLUTION TO A THREE PART ENGINEERING PROBLEM, RESULTING IN TRACTION UNDER ANY CIRCUMSTANCE. CONSTANT TRACTION EQUATES TO PREDICTABILITY, CONTROL, CONFIDENCE, AND ULTIMATELY MORE SPEED.
