Is the resivoir from the DHX-Air larger than the 5th coil? TNC was in a discussion with someone recently about the sizes of the different shock bodies.Fooly_CoolyOo said:The dhx air wont fit on your medium. It will only fit on Larges and X-larges. As for the size your looking for a 7.875 x 2.25. Try a Manitou Swinger 3 way, that should fit. They dont list the size on their web site but they make it. Just call them.
