Our epic trail and enduro bike for fast descents, technical terrain, and long days in the saddle.
The Lunchbox is built for riders who want to push harder on demanding trails without giving up climbing performance. Updated for 2026 with longer chainstays, a lower bottom bracket, and a longer reach, it delivers even more high-speed stability while remaining exceptionally capable on tight, technical climbs.
If your riding includes steep descents, rough terrain, and all-day missions, the Lunchbox is designed to meet that challenge. It combines confident geometry, progressive suspension, and modern compatibility in a package that feels composed when speeds rise and precise when the trail gets technical.
With UDH dropouts and Horst link suspension, the Lunchbox is ready for the latest components while delivering the ride quality serious trail and enduro riders expect. Its suspension is supple over small bumps, supportive deeper in the travel, and tuned to give you the control and stability you need when the trail turns rough.
The Lunchbox is designed to feel planted when the trail opens up and controlled when terrain becomes unpredictable. Its progressive rear suspension delivers a supple response over small chatter, then provides the deeper support needed for hard hits, rough landings, and sustained technical descending.
That balance gives riders the confidence to carry more speed, stay composed through difficult terrain, and keep pushing their technical riding further. At the same time, the Lunchbox remains an excellent climber, making it a true all-day trail and enduro platform rather than a bike that only comes alive on the way down.
Riders can configure the Lunchbox with either 27.5-inch or 29-inch tires depending on ride goals and terrain preferences. It performs well with tire widths from 2.4 to 3.0 inches, and mixed wheel builds are also available for riders who want a more specialized setup.
