TruTune Flow

Reduce fatigue, increase grip and comfort. Experience a coil-like feel without the weight penalty.
The a plug-and-play upgrade for mountain bike air forks. Powered by activated carbon, it increases effective air volume and reduces the speed sensitivity of air.
The result? Better small bump compliance, increased mid-stroke support and end stroke absorption.

Installs simply, just like a volume spacer. Release all pressure, remove the top cap, clip on or thread on the insert, and charge to our recommended pressure.

Smooth and comfortable feeling through the whole travel, reducing arm pump and fatigue and providing improved grip.
Provides a consistent stiffness, similar to a coil spring. This allows running higher pressure for exceptional support without running into harshness, or keeping pressure the same to unlock more travel.

Reduces speed sensitivity inherent in air springs, meaning the fork feels more predictable and does not stiffen up with faster movements. This is critical to reducing chatter and improving end stroke absorption.
