Cannondale's Trail SL 29er 6 is a legit mountain bike that's singletrack worthy. This hardtail starts off with Cannondale's famous large-diameter, thin-wall aluminum tubes to maximize stiffness and minimize weight. When your bike is lighter, you go faster, period. Add a SR Suntour suspension fork with 80mm of travel, and roots, rocks, you name it, don't stand a chance. Genuine Shimano parts make up the powertrain and give you plenty of gears so mountains turn into molehills beneath your huge wheels. These 29-inch wheels roll over obstacles easier. Combined with the dialed handling, this bike makes even first timers ride like experienced bikers.
