For nearly 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 4x 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, and 2021 sees the introduction of the 4th generation Mega. Designed as an evolution of the ultimate Enduro bike, the Mega 275 Carbon has been redesigned for 2021 to offer improved suspension kinematics and optimized sizing/fit on a brand new full-carbon chassis. Most importantly you can now fit a water bottle inside the main front triangle.
The Nukeproof Mega: an “enduro bike” that was ahead of its time. Originally developed and later named after the race it was designed for on the infamous trails of Alp D’Huez - the Megavalanche.
To date the Mega platform is one of the most highly decorated race bikes on the market: with 2017, 2018 (x2) and 2019 Enduro World Series Titles; a Downhill World Championship top 10 and a Silver Medal at the 4x World Championship to its name. (As well as a host of other national and international victories and titles!)
Since 2009 the Nukeproof Mega has been a constant path of development to meet the evolving demands of Nukeproof's riders and customers alike. Their team are relentlessly striving for improvements and with each generation, the Mega has been chiseled and shaped into today’s thoroughbred Enduro race bike. With the launch of the 2020 Carbon Mega 290c, you could forgive Nukeproof designers for resting on their laurels. However, as Nukeproof products are developed between the tapes, there is a constant desire to hone and refine in order to give their athletes and riders the best possible chance of standing on top of the podium.
To optimize the weight, strength and stiffness, the new 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. It is available for 27.5” or 29” wheel sizes. These are two 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 dialed fit, Nukeproof now offers 5 frames sizes: Small through to XX-Large with evenly spaced jumps between each.
Lower, longer, steeper and slacker! Nukeproof's new geometry is now designed around the saddle offset for each size to optimize 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 maximize 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 stoke for support when pedaling, 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.
