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. 2021 saw the introduction of the 4th generation Mega and the addition of the 297 MX wheelsize.
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 maximise grip and rolling efficiency whilst the 27.5” wheel out back, ensures nimble handling for manoeuvrability and extra clearance for riders when leaning off the back of the bike.
To optimise the weight, strength and stiffness, the Mega Carbon frame features a T700/800 UD woven carbon fibre 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.
With 4 Enduro World Series Titles in 3 years the V4 design is an evolution of the ultimate race proven enduro bike. At the heart of the frame is its 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. With a wide SAG range to allow riders to tune the suspension to the trails.
Other key features include:
- Front 29”/Rear 27.5” MX wheel size platform
- Optimised suspension kinematics
- Tube-In-Tube design for easy cable installation
- SRAM UDH
- On bike tool storage options
- Room for a 750ml water bottle inside the main front triangle
The 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.
