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 sees the introduction of the 4th generation Mega, now 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. This has resulted in the launch of the Mega 297.
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 weight, strength and stiffness, the Mega Carbon frame features a T700/800 UD woven carbon fiber frameset (Front and rear Triangle). The new carbon swingarms helps reduce the unsprung weight on the rear of the bike. All forged part are made from 6061-T6 Aluminium.
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 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:
- 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 optimize 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.
