RAGE-iS BRINGS INNOVATION BY COMBINING A HIGH PERFORMANCE DROPPER SEAT POST WITH ADJUSTABLE SUSPENSION. Introducing the revolutionary Rage-iS - a game-changer, entirely powered by air, that offers both drop and suspension travel. A Schrader valve nestled beneath the clamp allows you to fine-tune the spring pressure. Dial down the pressure for a plush ride over every bump. Prefer a firmer ride? Just add air. In both cases you keep full drop capabilities. Whether you're tackling tough mountain trails on a hard tail, exploring back roads on a gravel bike, or embarking on a long trek on a touring bike the Rage-iS' suspension system provides complete customization according to individual preferences.
