The Specialized Enduro SL 2010 Mountain Bike features the new X-Wing FACT IS carbon frame, which is 27% stiffer than the previous version. It is also almost a pound lighter, featuring 160mm of travel both front and rear, with a removable ISCG mount. To increase stiffness, the Specialized Enduro SL 2010 Mountain Bike sports beefy chainstays and dropouts. The FOX RP23 rear shock, made specifically for the Enduro, features 3-position ProPedal adjustment. The Future Shock E160TA fork, designed by Specialized, features 135-160mm of adjustable travel, so you can get it just the way you want it. Another interesting feature of the Specialized Enduro SL 2010 Mountain Bike is its remote-adjust command post, by Specialized, which automatically switches between three different saddle height positions just by clicking a handlebar-mounted lever; the three positions are Power position for climbs, Cruiser position for undulating terrain, and Descend position for downhill descents.
