Specialized Hardrock Sport Disc 2012 Mountain Bike

The Hardrock Sport Disc 2012 Mountain Bike by Specialized is popular due to its durability, versatility, and capability, whether cruising through urban environs en route to school or work, tearing up some local mountain singletrack, or poaching a shortcut through the woods to a friend's house.

Fully butted A1 Premium Aluminium frame with double ORE down tube for a lighter, more compliant and durable bike. 80mm smooth-travel SR Suntour fork with preload adjustment, lockout, and size-specific spring rates for more versatility and tunability over varying terrain. Specialized Fast Trak LK Sport 60 TPI tyres use a reduced knob height for lower rolling resistance, but have plenty of grip for confidence on the trail. Sealed cartridge bearing BB is durable and easy to service. Tektro Draco hydraulic disc brakes with dual pistons and forged callipers assure precision braking and durability. Light and durable double-walled alloy rims are tough enough to handle the rough stuff. SR's fully replaceable ring crankset uses Shimano's Octalink-splined BB interface for reliable power transfer; chainguard included. Shimano Acera 9-speed rear derailleur and Acera Rapidfire shifters for reliable high-end performance. Shimano 9-speed, 11-34t cassette offers gearing options for a variety of fitness levels.
