Hardrock Sport Disc

Hardrock Sport Disc

With a smooth SR Suntour fork with lockout, powerful Avid BB5 disc brakes, and double-walled alloy wheels, the Hardrock Sport Disc is prepared for mountain trails and urban jungles.

  • 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

Young rippers—and new rippers of every age—ride the Hardrock because of 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.

Frames made of corrosion-resistant aluminium tubing, utilizing ORE (optimised Radius Engineering) on the down tube.

Creates the best balance of light weight, strength, durability, and value.

By controlling everything from the raw material to the extrusion, butting, swaging, and heat treatment of the tubes, we can optimise our Hardrock bikes for the given ride experience. ORE, specifically, increases weld surface areas at tube junctions for greater strength, while shaving material in non-critical areas.

29-inch specific models available at sport and disc levels.

Provides faster and more efficient rolling on varied surfaces and makes it easier to get over obstacles.

Larger wheels maintain more momentum when rolling, making road riding more efficient. Off-road, the contact angle is less severe on square edge bumps, so 29” wheels roll over obstacles faster and easier than traditional 26” wheels. They also bridge wider gaps between rocks, which smoothes out bumpy conditions.

Double-wall alloy rims with alloy cassette hubs.

Longer wheelset life, quicker acceleration, and better control.

By using a different extrusion process, a second wall is added to the rim, which increases stiffness and strength with little weight penalty. And while some competitors use freewheel style hubs, our alloy cassette hubs dramatically increase stiffness and strength at the point of power transfer, while protecting the axle from bending.

80mm-travel alloy fork with pre-load adjust, size-specific spring rates, and oversized stanchions.

Better control and precise handling for a more responsive and comfortable ride on or off-road.

Combining a lightweight fork material with stiff, oversized stanchions and 80mm of smooth travel keeps the front wheel on the ground and tracking straight over rough terrain. Preload adjust dials in the perfect ride allow riders to achieve proper sag according to their specific weight and desired ride feel.
