Co-developed with Fox®, this highly advanced lightweight air shock was designed specifically to enhance Monoshock suspension performance. The Mega Float can actually improve ride comfort and anti-bottoming at the same time! This is due in part to the natural rising rate of the air spring. In the early part of the stroke, the spring rate is relatively low, enhancing small bump ride comfort with a very plush feeling. As the suspension compresses and the shock moves through its stroke, the spring rate goes up, helping to reduce bottoming on larger bumps. Air pressure is adjustable, so the rider can decide the priority between ride comfort and anti-bottoming. Lower the pressure and the ride gets plusher. Raise the pressure and anti-bottoming improves. By far the most capable shock absorber ever installed in a Monoshock rear suspension, the Mega Float is standard equipment on the 2011 Apex SE. But for anyone wanting to dramatically improve the performance of any other Monoshock rear suspension, the Mega Float is the ideal "plug and play" solution, as it will bolt right in. Only the air pressure needs to be adapted to suit the specific application. Comes with air pressure gauge pump.
