Curnutt AIR Shock – The Curnutt AIR is designed around Foes popular 2:1 leverage ratio and features technology not found on traditional air shocks. With Curnutt’s unique extra large air chamber, you can run a lower psi than the competition. Besides being easier to pump to on the trail, lower pressures promote small bump performance and increase traction. Although enjoying a weight benefit from the lack of a steel or titanium spring is definitely a plus – you can save a pound in weight over a titanium shod Curnutt coilover - the 2:1 Curnutt Air has the added benefit of flowing much more fluid than other shocks. This prevents damping fluctuations due to temperature shifts, and allows more precision in external damping and rebound adjustabilities. Simply put, the Curnutt 2:1 AIR is at the pinnacle of air shock damping performance and technologies, and is available only on Foes.
