Nukeproof Mega 275 RS Carbon Bike (XO1 Eagle)The Nukeproof Mega 275 RS Carbon is designed, engineered and equipped to push the upper limits of enduro racing performance. With a Nukeproof MegaV4 carbon frame that’s fitted with RockShox Zeb Ultimate forks and Super Deluxe Ultimate rear shock, it’s agile, efficient and stable – it’s suited to the most daring challenges on the mountainside. Also, it’s armed with a top-level SRAM Eagle 12-Speed groupset and a superb component spec throughout.SRAM XO1 Eagle 12-Speed Groupset with Code RSC Disc BrakesA SRAM XO1 Eagle 12-Speed groupset with Descendant Carbon cranks and Code RSC hydraulic disc brakes provide efficiency and stopping power for the steepest climbs and fastest descents. Plus, this full suspension bike is armed with a Nukeproof aftermarket finishing kit and a RockShox Reverb Stealth dropper seatpost. Finally, it rolls upon Sam Hill edition Mavic Deemax Pro wheels wrapped in Michelin Wild Enduro Gum-X Tubeless Ready tyres.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.Multiple World Series Championship VictoriesTo date the Mega platform is one of the most highly decorated race bikes on the market: with the 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!) Optimised Enduro Race PerformanceSince 2009 the Nukeproof Mega has been constant path of development to meet the evolving demands of our riders and customers alike. The Nukeproof team are relentlessly striving for improvements and with each generation the Mega has been chiselled and shaped into today’s thoroughbred Enduro race bike. With the launch of the 2020 Carbon Mega 290c, you could forgive their 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 Nukeproof athletes and riders the best possible chance of standing on top of the podium. Improved Sizing, Fit and GeometryDesigned as an evolution of the ultimate Enduro bike, the new Mega V4 has been fully reimagined for 2021 to offer optimised sizing/fit, improved Geometry and suspension kinematics on a brand new Aluminium chassis. Most importantly you can now fit a water bottle inside the main front triangle!High Quality Carbon Frame Construction:To optimise the weight, strength and stiffness, the new 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. 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.Updated Sizing/Geometry: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 5 frames sizes: Small through to XX-Large with evenly spaced jumps between each. Lower, longer, steeper and slacker! The Mega’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 we 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. Suspension Design: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 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 but can still be thrashed through the roughest and most technical terrain on the way back down.
