Nukeproof Mega 275 Carbon Factory Bike
Since 1999 the infamous Megavalanche race, which starts from the highest point on Pic Blanc (3300m) above the village of Alpe D’Huez has been synonymous with all mountain riding and the highest level of true mountain bike racing.
Conceived originally in 2009 by the development team at Nukeproof in an attempt to build the perfect bike for this exact style of racing, the Mega was born. Now in its 4th evolution, the Mega is podium proven. It has tasted success with numerous national and international race wins to its name.
Designed to excel on the toughest enduro tracks; the gravity focused specification is designed to descend fast but maintain the pedalling efficiency for all-day epics.
For 2019 Nukeproof has focussed on the smallest details in order to improve an already podium proven chassis. Making the decision to commit to a dedicated 1x drivetrain configuration across all models, this enabled its engineers to utilise the space required for a front derailleur to increase the main pivot bearing placement ensuring that maximum stiffness is achieved. This additional stiffness prevents torsional flex under pedalling and helps the chassis track through high speed, rough terrain without compromise.
With stiffness in mind, Nukeproof took the time to incorporate the very latest Boost 148 rear axle spacing allowing it to spec much stiffer and stronger wheels both front and rear. All 2019 Nukeproof Mega models will come with new wider spaced Boost wheels and forks enabling the rider to feel even more confident on the increased capability of the bike.
Updated Race Geometry
With the demands of Enduro World Series racers progressing at a rapid rate, Nukeproof looked again at its geometry and saw an opportunity to tailor the frames to suit not only the fastest racers, but the growing tribe of riders that utilise its bikes every weekend whether that be shuttling runs at their favourite bike park, or heading off for an all-day epic in the local hills.
Slightly taller head tube lengths help tailor the cockpit feel to increase rider confidence, and a lengthened top tube on large and extra-large frames should help even the tallest of riders feel at home on the new Mega 275 Carbon Factory.
Metric Shock Sizing
The product development team work extremely closely with Nukeproof’s suspension partners and spent endless hours working on the perfect shock configuration for the new Mega. The perfect partnership between rear shock technology and frame kinematics has always been in the very root of its thought process when developing bikes and the new Mega with its brand new ’metric’ shock standard is no different. Designed to work perfectly with both air and coil sprung rear shocks, Nukeproof has addressed some of the areas that it felt could be improved on over the previous design such as hardware improvements and higher spec shocks across the board.
The new Mega 275 Carbon Factory utilises the incredible Fox Float X2 rear shock and hardware now comprises of a wider spaced 25mmx8mm front mount. This combination adds even more stiffness to the chassis through these more secure fixtures and the ‘Metric’ rear shock system with increased bushing overlap.
High in Fibre
Leaning on its experience from the development of its award-winning Warhead Carbon handlebar range, Nukeproof has spent 4 years in the development of the brand new Mega 275 Carbon Factory. Utilising a blend of the highest quality carbon fibre composites, the Mega 275 Carbon Factory has been hand crafted with 1 goal in mind… Winning!
Not only is the chassis now significantly lighter than its aluminium counterpart, the strength and reliability of the frame has been vastly improved enabling every rider to push harder, faster and with more confidence than ever before.
Tested on the toughest of terrain and in the most varied conditions by Enduro World Series Winner Sam Hill, the 2019 Mega 275 Carbon Factory sets out to tackle every ride with its trademark attitude.
Pro set up tips:
Some tips on how to set up your Mega 275c:
Sam Hill, Nukeproof athlete:
As Sam runs on a Stock Rockshox Super Deluxe and Rockshox debonair:
Fork- 25% 2 spacers (gray) rebound -8(fully closed then turned out, counter clockwise) compression +5
Rear shock- 30% 2 spacers rebound -6(6 clicks out from full slow) compression +2
Nigel Page, Team CRC-Mavic Team Manager:
1 – 2 tokens in my fork and don’t have any bands in the rear of my shock
Sag I’d go for just shy of 30% front and rear.
Start with about 6 clicks of rebound back from all the way slow and go from there. Some riders prefer 1 or 2 clicks slower or faster. Same on the Shock and Fork.
Dale, Nukeproof engineer:
Tokens in forks – 1 as standard
Bands in rear shock – 0 tokens
Sag/ pressure in fork – this is personal preference (I use 75-80 psi)
Sag/ pressure in shock – 30% sag (I use 170 psi)
Clicks of compression – no adjustment on rear shock – 3 clicks of low speed compression on fork.
Clicks of rebound – I use 4 clicks on, riding clips
