We all remember our first mountain bike. For many of us, it was a bike like the Lana'i. It's affordable enough not to feel too risky but stocked with components that give you the freedom to explore off-road. The Lana'i features integrated Shimano shifters and brake levers to streamline the cockpit and is now available in three wheel sizes: 26" for size XS, 27.5" for S and M, and 29" for L and XL. With a Shimano drivetrain, Tektro disc brakes, and a 100mm travel fork, the Lana'i is the perfect way to dip your toes in the dirt. Kona 6061 Aluminum Kona 7005 and 6061 Aluminum alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, light alloy, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 tubing is butted and/or formed, meaning the tubing’s wall thickness can be increased or decreased as well as shaped, so we can fine-tune a particular frame’s strength and ride characteristics depending on its intended application. Internal Headset Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. Tapered Head Tube More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.

The Lava Dome is kind of like your best friend, but in bike form. It's awesome in the dirt. It's awesome to rally around town.

An 11-speed drivetrain makes quick work of tough hills ensuring the Mahuna is as fun going up as it is going down.

Developed with the Giant Factory Team riders who push the limits of their bodies and bikes week in and week out, this bike is made to boost confidence and shave seconds on the most punishing enduro terrain. We engineered the geometry of the Advanced composite frame and swingarm around larger diameter 29-inch wheels. That means shorter chainstays, a longer toptube, and just the right angles with the headtube (64.56 degrees) and seattube (76.36 degrees). We gave it an updated Maestro rear suspension system with 146mm of travel. The trunnion mount shock and Advanced Forged Composite rocker arm deliver an active, super plush feel on the trail. Other features including a cleanly routed dropper seatpost and a new Giant WheelSystem with Boost hub spacing and tubeless tires complete this race-ready package.
