This year’s Giga, Mega, and Reactor: same, but different. Over the past year, the Giga, Mega, and Reactor have proven themselves in media tests, on the race course, and as the bikes of choice for countless mountain bikers across the globe. So, we figured, why mess with a good thing?
For 2023, the main changes on our core line of carbon full suspension mountain bikes are spec changes and some glorious new coats of paint. Mid and top-tier specs feature the new SRAM AXS Transmission for the latest in shifting and other no-compromise componentry.
The Giga earned several nominations of enduro and bike park bike of the year from a number of publications and continues its winning ways at the Enduro World Series and in countless national victories. It has also been put to the test by several of our freeriders in some of the biggest terrain in the world.
Historically our flagship enduro model, the Mega is our best-selling model in the full suspension range. It has proven itself as the Nukeproof-SRAM Factory racing team’s bike of choice, and it’s the weapon Dan Booker is using in his hunt for the overall enduro world series title.
The Reactor is our Goldilocks trail bike: it’s not too big, not too small — it’s just right. A firm favorite among Nukeproof riders, the Reactor climbs with ease and descends like a hooligan. It defies its “short travel” status in the Nukeproof lineup and is a great option for big days in the saddle.
New Specs
While the frames remain the same, the new iteration of the Mega carbon and Giga carbon get all-new specs — namely, the new SRAM AXS Transmission.
The RS models are outfitted with the full SRAM X01 Eagle AXS Transmission, while the Factory models are a blend of the SRAM Xo/GX Eagle AXS Transmissions.
Elite models are outfitted with the full SRAM GX Eagle AXS Transmission system, and the Giga Carbon Comp is specced with the Microshift Advent-X
As always, these new builds are paired with the latest custom-tuned suspension packages from RockShox and Fox. In all, it’s the best-equipped line up we’ve ever produced.
The Giga
The Nukeproof Giga came to be because we wanted a bike with a little bit more; something that could still comfortably pedal uphill but would descend like a hooligan.
Thus came the Giga, a long-travel weapon designed around an evolution of the Dissent downhill bike’s fallout suspension linkage. It’s hugely capable, equally at home on the enduro world cup as it is lapping the gnarliest downhill trails in the park.
The monocoque UD carbon frame is internally piped for easy-fit cable routing, the downtube is sculpted to easily fit a water bottle, and the seat tube is designed to maximize post-insertion depths, allowing riders to run longer dropper posts. To ensure the Giga is protected, the frame comes fitted with 3D-moulded rubber protection and a factory-fitted clear paint protection kit.
Available in both 290 and 297 mixed-wheel options, the Giga features ultra-tuneable geometry and a top-notch component package.
RS:
£6499.99 GBP / $7,699.00 USD / €8099.99 EU
The RS spec of the Nukeproof Giga is our Nukeproof-SRAM Factory racing replica. It’s built around the latest RockShox Ultimate suspension. Out back the RockShox Super Deluxe Ultimate air is custom-tuned to maximise performance and soak up even the roughest terrain. With 180mm of travel up front from the RockShox ZEB Ultimate Charger 3 taking the hits.
The biggest update to this spec is the addition of the latest SRAM XX/XO Eagle Transmission. The switch to SRAM T-Type comes with huge benefits, including a vastly improved ability to shift under load — meaning riders can find the gear they want when they want it.
To finish the RS spec, it's equipped with a full suite of our premium-tier Nukeproof Horizon Components, as used by the Nukeproof-SRAM Factory team. Fast engaging, reliable, and tough Horizon wheels are wrapped in ultra-grippy Michelin Wild Enduro tires.
The RS is the ultimate specification of Giga.

It’s a hard-hitting setup, to say the least.
The Giga Elite comes with the all-new SRAM GX Eagle AXS 12-speed Transmission. Designed to be durable, GX Eagle T-Type offers on-point shifting time and time again. This system is easy to get dialed and maintain.

The Giga Comp is ready to roll straight from the shop floor to any enduro or bike park with the Maxxis Assegai and High Roller combo. While the Giga Comp is the entry point to the Giga range, it’s far from “entry level” performance.
Nukeproof Mega
An enduro bike built on the tenets of balance, predictability, and absolute speed.
Originally designed as the “downhiller’s trail bike” made specifically to tackle the infamous MEGAVALANCHE enduro in France, the Mega frame has evolved with the sport over the years. No matter the version, its performance remains consistent: the Mega keeps racking up enduro stage wins and press accolades. With no less than four Enduro World Championship titles to its name, the Mega has become an icon synonymous with Enduro racing.
This latest iteration of the bike — the Mega v4 — is built around a horst link suspension design. No matter the terrain, it inspires confidence with a subtle feel in the top of the travel that remains progressive and predictable through to the end of the stroke.
The Frame sizing is designed around our “dynamic saddle offset geometry” to optimize seated riders' weight distribution on each frame size, with sizes available ranging from small to XXL.
Available in both a standard 290 and 297 mixed-wheel configuration, riders can choose which version of the Mega suits them best.
