Jamis Hijack A2
Details
This is for those looking to take their trail riding to the next level. With modern geometry, a 5” travel fork with thru axle and tubeless rims, the Hijack performs as a capable all around hardtail.
Frame Materials
Lightweight and strong triple-butted 6061 series aluminum tubing, featuring over-sized & tapered tubing for increased frame stiffness.
Tapered Headset
Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A full 1.5" head tube and steerer would achieve this, but would add unnecessary weight and bulk, and limit stem choices. But a tapered 1 1 /8" to 1 1 /2" head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8" systems.
Why Thru Axles?
The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.
