Don’t hold back, Specialized’s Hellga Expert is ready to give you the ultimate in versatility by providing superb traction, floatation, and control on all kinds of terrain. This lightweight aluminum frame, fronted with a vibration-smoothing FACT carbon fork, practically hovers on 4.6-inch Ground Control tires that let you enjoy the simple pleasures of superb traction in loose sand and snow. The super-wide aluminum rims give you stability and durability to let you float over roots and rocks. SRAM’s efficient one-by 11-speed drivetrain provides slick shifting on all-day adventures or snowy cruises. You can bring it all back down to earthly limits with excellent speed modulation thanks to the Shimano Deore XT hydraulic disc brakes. And this fat bike is loaded with Specialized's bar, stem, post, and renowned Body Geometry saddle.
