Features

Calibre's award-winning full-suspension mountain bike, available exclusively at GO Outdoors.

Just awarded MBR's Bike of the Year 2015, the Calibre Bossnut has been designed for both newcomers and experienced riders, with geometry that's tuned for confidence-inspiring stability and able to respond sharply to aggressive riding.

This full-suspension bike will help you conquer those rough, steeper terrains that a hardtail simply can't handle, giving you plenty of scope for future upgrading as your riding progresses.

It has a double-butted aluminium frame with a smooth-welded front triangle and a single pivot swing arm designed around 130mm travel platform, giving an ideal amount of suspension for all-round trail riding.

The RockShox Sektor Silver Solo Air fork and the Monarch R rear shock offer plush air-sprung suspension with rebound adjustment, the front fork being lockout-equipped for efficient pedaling when suspension isn't required. The rear shock maintains traction over rough ground, giving you greater control of your bike and letting you power through terrain that would previously have you grabbing your brakes.

The full Shimano Deore 2x10 groupset includes a clutch-equipped Shadow+ rear mech for improved chain retention, rugged enough to take serious trail abuse whilst still providing precise, efficient performance. The Shimano hydraulic disc brakes, and their integrated I-spec lever design, bolts together with the gear levers for a tidy, easy-to-use cockpit.

Deore hubs and tubeless-ready WTB ST i25 rims continue the upgrading theme, allowing you to make the move to tubeless tyres with a minimum of fuss. The WTB Vigilante sits on the front wheel to provide extra control and grip while cornering, while the Bee Line's lower tread keeps the rear wheel rolling fast.

Ritchey provide their famous high-quality aluminium components for the seatpost, stem and handlebars with their Trail Rizer bars right on trend for the modern trail rider at a 760mm width.

The Bossnut Ladies is also now available, designed with a women's specific size and components. Please click here for more information.
