Infinite Rate Tune (IRT) allows for advanced spring tuning by independently adjusting air pressures in the beginning and end stroke. IRT technology creates a secondary positive air spring that affects only the middle to end stroke of the fork. This allows the main air spring to be set to lower pressures for improved small bump sensitivity while maintaining mid-stroke support and moderate to aggressive end-stroke ramp-up. and
