IRT Infinite Rate Tune

Infinite Rate Tune (IRT) is a two-stage air spring configuration that allows for advanced spring rate tuning by independently adjusting air pressures in the beginning, mid and end strokes. The IRT secondary positive air spring affects only the middle to end stroke of the fork. This allows the primary air spring to be set to lower pressures for improved small bump sensitivity while maintaining independently adjustable mid-stroke support and end-stroke ramp-up.
