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 for 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 line-up and is a great option for big days in the saddle.

While the frames remain the same, the new iteration of the Mega carbon and Giga carbon get all-new spec—namely, the new SRAM AXS transmission. The RS models are outfitted with the full SRAM XO Eagle AXS Transmission, while the Factory models are a blend of the SRAM XO/GX Eagle AXS Transmissions. The Elite models are outfitted with the full SRAM GX Eagle AXS Transmission system. As always, these new builds are paired with the latest custom-tuned suspension packages from Rockshox and Fox. Lastly, the Giga carbon Comp is specced with the Microshift Advent-X 10-speed drivetrain, a durable and high-performing option that’s been tested and used at the highest level by our pro-enduro athletes. In all, it’s the best equipped line up we’ve ever produced.
