A super fast and extremely lightweight full-carbon road bike, designed exclusively for GO Outdoors.

If you're a keen cyclist with an eye on races and sportives, then the Calibre Nibiru 2.0 Bike will help take your cycling to the next level.

The Nibiru frame is constructed from high quality Toray T300 carbon fibre throughout to ensure excellent strength, weight and performance, with internal cable routing for extra aerodynamic advantage.

Vibration-dampening is promoted in the forks and seat stays for comfort in the saddle and handlebars, whereas stiffness is promoted around the bottom bracket and headtube for efficient pedaling and stable handling.

Smooth, reliable shifting and efficient power transfer, with effortless precision, are assured thanks to the full Shimano 105 11-speed groupset.

The Shimano wheelset combines their fast, light RS11 model with a semi-aero 30mm rim profile to help you cut through the air at speed, with smooth rolling Continental Ultrasport II tyres.

A Selle Royal Seta keeps things comfy in the saddle department, while the lightweight Ritchey aluminium stem, handlebars and seatpost take care of the rest of the contact point components in style.
