An enduro bike built on the tenets of balance, predictability, and absolute speed
Originally built as the “downhiller’s trail bike” made specifically to tackle the infamous MEGAVALANCHE enduro in France, the Nukeproof Mega has been racking up enduro stage wins and press accolades for over ten years. With four Enduro World Series titles to its name, the Mega has become an icon synonymous with racing.
Since 2009 the Nukeproof Mega has been on a constant development to meet the demands of our riders and customers alike.
Available in both a standard 290 and 297 mixed-wheel configuration, you can choose which version of the Mega suits your riding best — either the stability of a matched 29” setup front and rear, or the quick and playful pairing of and 29” front wheel and 27.5” wheel in the rear.
Currently in its fourth generation, the Mega is the product of more than ten years of refinement. It’s progressive, predictable, and downright fast; a bike as much at home between the tape at an Enduro World Series as it is bombing sketchy rock gardens on your home trails.
In pursuit of optimizing weight, strength, and stiffness, the Mega 297 Carbon is built around full T700/800 UD woven carbon fiber front and rear triangles. Its long, low, and slack geometry is designed around our saddle offset principle, which adjusts seat tube angle across the size range to ensure the seated riding position is perfect, no matter the rider’s height.
Everything on the bike has been carefully designed for racing and hard enduro riding. We've carved out space inside the front triangle of the frame for a 750ml water bottle, the seat tube is designed for slammed dropper posts, and we’ve even fitted the Mega with a threaded bottom bracket and universal derailleur hanger for easy maintenance.
The Mega’s Horst-link suspension system is tuned for suppleness over small bumps while remaining supportive on the climbs. Solid mid-stroke support balanced with relatively modest anti-squat gives the Mega an active rear end that feels shockingly efficient when pedaling uphill. Anti-squat reduces as you shift down the cassette and pick up speed, making the bike come alive on descents
After winning 4 Enduro World Series Titles in 3 years the all new design is an evolution of our ultimate Enduro bike. At the heart of the frame is suspension Kinematics, designed to be more subtle off the top, whilst remaining progressive and predictable . Anti-Squat is used to create an effective pedalling bike that can be thrashed through technical terrain. The useable SAG range is also widened to allow riders to tune the suspension to the trails. Other key features include:
- All New Carbon chassis
- Designed and improved suspension kinematics
- Tube In Tube design for easy cable installation
- All new Geometry
- Optimised sizing/fit - Small to XXL (290 M to XXL, 297 S to L
- SRAM UDH
- Now fits a 750ml water bottle inside the main front triangle!
The Mega frame is optimised around the rider and weight distribution. The new geometry features dynamic saddle offset. Seat angles are optimised for each frame size and the seat tube itself is designed to take a longer dropper post if required.
