The Giga is a seriously capable machine, with 180 mm (27.5”) or 170 mm (29”) rear travel; the Giga is a monster truck of a bike that has travel in reserve for when you need it. But to pigeonhole it as a point and shoot machine would be a disservice, as it is so much more capable than this might suggest! Due to the way that it uses its travel; the Giga gives you the feel of a big bike, yet the versatility of a modern super-enduro bike. The Giga has a dynamic and confidence inspiring ride to help you push your limits in all kinds of terrain. It’s equally at home at big mountain technical enduro stages of venues like La Thuile, as it is lapping the biggest lines in the Whistler bike park.  

The suspension is designed to be super supple off the top, whilst being supportive in the mid-stroke and progressive throughout the rest of the travel. The anti-squat is optimised to ensure the Giga descends like a hooligan yet behaves itself on the climb back to the top for the next run.

The suspension platform is based on the same horseshoe driven linkage as Nukeproof's award-winning Dissent downhill frame, albeit now with a 2-stage main pivot flip chip. Using an eccentric axle system, riders can alter the Kinematic progressivity; so the bike can be tailored to suit the conditions on the trail with only an 8 mm allen key.

  • Setting 1 = 25.5% progression 
  • Setting 2 = 29% progression. 

Both settings have a super supple beginning for small bump compliance. They also both have good mid-stroke support for better cornering and pumping. Like the Dissent, the progression drops off in the end stroke to prevent mid-stroke harshness or spiking and allows more tuning options with volume spacers. 

The "+" Progressive setting can be used to add shock progression on a coil set up, just like adding a volume spacer to an air shock. The added suppleness is also good in wet and slippery conditions. 

The Giga Frame is constructed completely from UD 700/800 Carbon fibre. This allowed Nukeproof to optimise the stiffness and compliance of the frame parts individually. The front triangle has been tailored for stability and precision, whilst the rear triangle was designed for compliance to help tracking and provide grip. Another bonus of the carbon rear triangle is that it has a lower unsprung mass for ultimate suspension performance.

Available in 5 sizes (Small to XXL) in either mixed, 27.5 (frame only) or 29” wheel size, there is the perfect fit for everyone. The frame geometry is Long, Low, Slack and Steep as it is based around Nukeproof's saddle offset principle, which ensures the seated riding position is tailored across all sizes, with steeper seat angles on bigger frames. The Seat tube is also designed for maximum seat post insertion to allow maximum drop.

The Giga is also sculptured to fit a 750ml water bottle (carbon bottle cage included) as well as an accessory mount under the top tube for emergency trail tools. All models also feature an integrated rear mud guard and plenty of clearance for up to 2.5” tyres. The frames feature a clear paint protection kit as standard with 3D contoured rubber downtube, seat and chain stay protection.
