About Specialized Enduro SL Comp: All-day trail sessions are what Specialized's Enduro SL Comp is all about. Its FSR suspension provides bump-busting travel without sacrificing efficiency. And, the light M5-aluminum frame is strong enough to handle the demands of tough trail riding. The Specialized Future Shock fork and AFR rear suspension provide a balanced 150mm of buttery smooth travel front and rear. And, the Avid Juicys let you push the limits of speed without sacrificing control. Plus, with a 27-speed SRAM/Shimano drivetrain, the Enduro gets you back to the top so you can do it all over again.
