For 1998, Schwinn added the "All Mountain" series to the line of Homegrown full suspension bikes featuring John Castellano's Sweet Spot® URT design. The Homegrown All Mountain frames were made in Taiwan by Top Key and fitted with a Rock Shox Coupe Deluxe coil-over rear shock, providing the same 3.75 inches of travel as the Homegrown Factory Suspension frames. The seat tube and head tube angles were relaxed .5° and the top tube was slightly lengthened in conjunction with the use of a 100mm travel fork on the Homegrown All Mountain in place of the 80mm travel on the Homegrown Factory Suspension.
The Homegrown All Mountain LXT shared the more-expensive Homegrown All Mountain XT's frame, rear shock, and dual-crown Rock Shox Judy XL suspension fork but was fitted with a Shimano Deore XT group, excluding the Deore LX crankset. Hayes hydraulic levers and calipers provided the braking, with the rear brake using Hayes' 22mm direct mount.
