Nukeproof Giga 297 MX Mountain Bike 2022 - Enduro Full Suspension MTB
As riders, we are all guilty of the gluttonous sin; we never stop striving, never stop pushing, enough is never enough in the hunt for the ultimate. It’s a constant push for bigger, longer, rougher, and faster with ever increasing demands on the performance and capabilities of our bike. The pursuit is endless, and the result is that the Giga is now available in an all-new 297 MX platform.
The Nukeproof Giga is the embodiment of this idea; Designed to be the ultimate hard-hitting Super-Enduro weapon for when you just need more.
The Giga is now available for 275, 290 or 297 MX (Front 29”/Rear 27.5” wheel sizes) wheel set ups, with each frame design tailored around each wheel size.
The 297MX uses a 29” wheel up front to maximise grip and rolling efficiency and replaces the 29” with a 27.5” wheel out back. The smaller 27.5” rear wheel ensures nimble handling and extra clearance for riders when leaning off the back of the bike (Especially on steep terrain).
Whatever the wheel size; the Giga a seriously capable machine, with 180mm (27.5” or 29”/27.5”) or 170mm (29”) rear travel; the Giga is a monster truck of a bike that has travel in reserve for when you need it. But to pigeon-hole 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 ouraward-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; the bike can be tailored to suit the conditions on the trail with only an 8mm 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 us 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 un-sprung mass for ultimate suspension performance.
To ensure a perfectly dialled fit we now offer the 297 bikes in S, M, or L sizes and the 290 bikes in M, L, XL or XXL.
The frame geometry is Long, Low, Slack and Steep as it is based around our 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.
Occasionally, without notice, manufacturers change product design and/or specifications.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
