RAMP'AIR Air Chamber for RockShox BoXXer 38mm Fork from 2024

Unlock the full potential of your air suspension fork.

The RampAir system adds a dynamic second air chamber with a floating piston to the main chamber, delivering a linear, precise, and controlled response — the COIL feeling!

More grip, more control, more safety on all terrains. Precision-engineered from high-quality aluminium, it requires low maintenance and is fully rebuildable.

Achieving a linear, consistent spring curve with air suspension is difficult, as air behaves exponentially when compressed.

As a result, conventional air forks often lack crucial mid-stroke support, i.e. stability in this range.

To compensate for this shortcoming, many manufacturers opt for overly firm compression damping.

As a result, mountain bikers reduce air pressure to maintain sensitive response to small terrain irregularities.

However, due to a lack of mid-stroke support, many tend to use volume spacers to remedy this, which only further increases the curve's excessive progression at the end of the travel.

The result is unbalanced suspension: either you lose sensitivity at the expense of grip and comfort, or you sacrifice control and cornering stability.

RampAir intelligently solves this problem: the system harnesses the natural progression of air to create a linear, controlled spring curve.

You benefit from high-performance suspension throughout its entire travel: supple at the start of travel, supportive mid-stroke, and controlled at the end of travel. The pressure in the main and RampAir chambers is individually adjustable, allowing you to tailor your suspension perfectly to your riding style and the terrain.
