The Mega 297 Pro Alloy features a mixed wheel platform with a 29"-wheel up front and a 27.5" at the rear, giving the optimal balance of fast-rolling, all-terrain stability mixed with playfulness and agility. It also has a durable and lightweight custom-butted alloy frame with 170mm-travel RockShox ZEB suspension forks and a Super Deluxe rear shock. Ideal for riding with pace, stability and control over the most challenging terrains on Earth, the Mega Pro 297 is ready for anything.
This Mega 297 Pro is kitted out with a SRAM GX Eagle 12-Speed groupset that includes a wide-ranging 10-52T cassette and SRAM Guide RE hydraulic disc brakes. Nukeproof has it rolling upon Tubeless Ready Nukeproof Neutron V2 wheels wrapped in Maxxis Assegai and Minion DHR Tubeless Ready tyres. And it's fitted with a Brand X Ascend internally cable routed dropper seatpost.
For over 10 years, Nukeproof's 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, Nukeproof never rests on their laurels with the 4th generation Mega - Now available in an all-new mixed wheel size platform.
Since 2009 the Nukeproof Mega has been on a constant development to meet the demands of our riders and customers alike.
The Mega V4 is now available for 27.5”, 29” or new Mixed (Front 29”/Rear 27.5” wheel sizes) wheel setups, with each frame design tailored around each wheel size. The new mixed platform uses a 29” wheel up front to maximise grip and rolling efficiency whilst the 27.5” wheel out back, ensures nimble handling for manoeuvrability.
Designed as an evolution of the ultimate Enduro bike, the Mega V4 has been fully reimagined to offer optimised sizing/fit, improved Geometry and suspension kinematics. Most importantly you can now fit a water bottle inside the main front triangle.
The Alloy Mega features a full custom triple-butted hydro-formed 6061-T6 Aluminium tube set and forged parts. It is available for 27.5”, 297 or 29” wheel sizes. These are totally different, compromise-free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size so that you can get the most out of every ride.
Whilst humans may not have changed size much in recent years; the bikes they choose to ride most certainly have. To ensure a perfectly dialled fit Nukeproof now offer 297 bikes in S, M, or L sizes and 290 bikes in M, L, XL or XXL.
Lower, longer, steeper and slacker. Nukeproof's new geometry is now designed around the saddle offset for each size to optimise seated weight distribution. This results in steeper seat angles across the board but especially on larger sizes for taller riders. This in turn results in longer reach figures to ensure a comfortable cockpit on each size. To further aid the perfect fit they have also used shorter seat tubes which are designed to maximise seat post insertion depths. Finally, all new Mega bikes are now designed to use short offset forks to further improve both climbing and descending capabilities.
To step-change the Mega’s suspension design Nukeproof went back to the drawing board and started afresh. They redesigned the Mega 4 bar horst linkage to be super supple over small bumps, progressive and supportive throughout the mid-stroke for support when pedalling, cornering and pumping, with increased end stroke leverage to allow more tuning options with volume spacers. The new kinematic is designed to have higher levels of anti-squat for climbing gears but this reduces as you drop down the cassette. The result is a bike that is more confidence-inspiring everywhere on the hill. It behaves itself on the climbs yet can still be thrashed through the roughest and most technical terrain on the way back down.
