Kona Blast 27.5" Mountain Bike 2020 - Hardtail MTB
The Blast dabbles deeper into mountain biking’s trends. With a Shimano 1x drivetrain, larger tire clearance, tubeless-ready rims, a RockShox air-sprung fork, Shimano hydraulic disc brakes and 27.5” wheels, the Blast steps it up, ensuring you have the confidence needed to tackle tougher trails and grow as a rider. Available in S-XL.
KONA RACE LIGHT 6061 ALUMINUM - Kona Race Light 7005 and 6061 are lighter, more performance-oriented fabrications of our 7005/6061 tubing. Designed to meet Kona’s discerning race specifications, Race Light 7005/6061 are custom butted to create thicker tubes at weld areas and important parts of the frame, providing incredible strength and torsional integrity to the feel of the ride. We remove wall thickness in other parts of the frameset to lighten up the bike, giving the perfect balance between quickness and stiffness.
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.
TUBELESS COMPATIBLE RIMS - Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems.
27.5" WHEELS - The benefits of the 27.5-inch wheel are simple: they roll over obstacles and track better than 26-inch wheels, but are more manoeuvrable and nimble than 29-inch ones.
Occasionally, without notice, manufacturers change product design and/or specifications.
