Kona USA's Kevin Noble's Raijin prototype test bike. A build kit specifically selected for wet, dark, deep NW Washington singletrack

Due for release in early Spring 2012, the Kona USA product and testing group has been hard at work on a new titanium hardtail 29-inch wheel mountain bike – the all-new Raijin. With a long history in titanium design, and some serious expertise in designing unique, industry leading 29-inch wheel bikes, the new Raijin comes loaded with cool custom features, on a frame designed by Kona and manufactured in the USA by Lynskey Performance Designs.

The Raijin (the Japanese god of lightning and thunder) is all about maximizing the inherent virtues of titanium with geometry ideally suited to fast, efficient, simple, and ridiculously fun singletrack riding. Our Kona USA product testers are loving every minute riding their prototypes, so much so we’re having a hard time keeping them in the office.

The Raijin will be available as a frameset only in early April, 2012. Suggested retail is $1,899USD with a target weight of approximately 4-pounds (1.8kgs) for an 18-inch frame. It comes in a raw, industrial mill finish with lazer-etched graphics and features a stylish Kona engraved logo on the driveside chainstay yoke.

The super sexy Raijin frameset is made using 3/2.5Ti tube material with a shaped downtube that is curved at the headtube. The design aims to perfectly balance the need for both stiffness and compliancy in a trail bike. We take all that we’ve learned in 29, hardtail and titanium bike design and create a trail master that channels rider forces perfectly, while at the same time using the compliant nature of titanium to take the edge of off trail feedback. All in all, a real gem of a bike, designed specifically for the discerning mountain cyclist.

* Press fit BB30 bottom bracket
