Nukeproof Mega 297 Alloy

Nukeproof Mega 297 Alloy

For over 10 years, our best-selling model; the Mega has been racking up awards on Enduro stages and in the press around the world. With 4 Enduro World Series titles to its name, the Mega has become an icon that is synonymous with racing. However, we never rest on our laurels and 2021 saw the introduction of the 4th generation Mega, in a 297 offering.  

Since 2009 the Nukeproof Mega has been on a constant development to meet the demands of our riders and customers alike. 

The pursuit for performance is endless. Developed in conjunction with our elite athletes, the Mega is now available in a mixed (MX) wheel size platform. The Mega 297 is a seriously capable machine, paring a 29” wheel up front with a 27.5” wheel out back. Why two sized wheels? The 29” wheel up front to maximize grip and rolling efficiency whilst the 27.5” wheel out back, ensures nimble handling for maneuverability and extra clearance for riders when leaning off the back of the bike.  

To optimize the strength and weight, the Mega is constructed fully out of T6061-T6 Aluminium including all forged part.

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 all new suspension Kinematics, designed to be more subtle off the top, whilst remaining progressive and predictable. Anti-Squat is used to create an effective pedaling 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: 

  • Front 29”/Rear 27.5” MX wheel size platform 
  • Improved suspension kinematics 
  • Tube-In-Tube design for easy cable installation 
  • All new Geometry  
  • SRAM UDH 
  • Room for a 750ml water bottle inside the main front triangle 

The new Mega frame geometry features dynamic saddle offset which is designed to optimise seated rider weight distribution on each frame size. This is achieved through seat angle which are bespoke to each frame size. In addition, the actual seat tube is designed to be shorter overall with a bigger maximum insert depth so as to allow a longer dropper post if required.
