Nukeproof Mega 275 Alloy Mountain Bike Frame. 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 & 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 275 is podium proven. It has tasted success with numerous national & 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 Chassis Stiffness. For 2019 Nukeproof has focussed on the smallest details in order to improve an already podium proven chassis. The Mega’s frame now has a dedicated 1x drivetrain configuration, increasing the main pivot bearing placement to maximise frame stiffness. This additional stiffness prevents torsional flex under pedalling & 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 & stronger wheels both front & rear. All 2019 Nukeproof Mega models will come with new wider spaced Boost wheels & 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 & 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, & a lengthened top tube on large & extra-large frames should help even the tallest of riders feel at home on the new Mega 275 Carbon RSMetric Shock Sizing. The product development team work extremely closely with Nukeproof's suspension partners & spent endless hours working on the perfect shock configuration for the new Mega. The perfect partnership between rear shock technology & frame kinematics have always been in the very root of its thought process when developing bikes & the new Mega with its brand new ’metric’ shock standard is no different. Designed to work perfectly with both air & coil sprung rear shocks, Nukeproof has addressed some of the areas that it felt could be enhanced on over the previous design such as hardware improvements & higher spec shocks across the board The new Mega 275 Carbon RS utilises the brand new Rock Shox Super Deluxe rear shock & hardware now comprises of a wider spaced 25mmx 8mm front mount, with a rocker link mounted bearing system to improve shock sensitivity & reduce the amount of wear through heavy usage. This combination adds even more stiffness to the chassis through these more secure fixtures & the ‘ Metric’ rear shock system with increased bushing overlap

Nukeproof Mega 275 Alloy Mountain Bike Frame The Mega 275 Alloy Frame features an Enduro World Series proven design that was optimised in partnership with Sam Hill. This full-suspension pro race frame is also equipped with Rock Shox Super Deluxe Ultimate RCT rear shock that's custom tuned to ensure the greatest performance anywhere. &, with tyre clearance for 2.6" tyres, an ISCG05 chainguide mount, internal cable routing, Boost 148mm rear spacing & Enduro bearings throughout, this frame is prepared for everything the mountain throws your way. Introducing the All-New Mega V4: Born Through Evolution, Not Revolution The Nukeproof Mega: an “enduro bike” that was ahead of its time. Originally developed & later named after the race it was designed for on the infamous trails of Alp D' Huez
- the Megavalanche. Multiple Enduro World Series (EWS) Victories To date the Mega platform is one of the most highly decorated race bikes on the market: with the 2017, 2018 (x 2) & 2019 Enduro World Series Titles; a Downhill World Championship top 10 & a Silver Medal at the 4x World Championship to its name. (As well as a host of other national & international victories & titles!) Refined & Optimised for World Class Performance Since 2009 the Nukeproof Mega has been constant path of development to meet the evolving demands of Nukeproof's riders & customers alike. Their team are relentlessly striving for improvements & with each generation the Mega has been chiselled & 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 & refine in order to give their athletes & riders the best possible chance of standing on top of the podium. enhanced Geometry & Suspension Kinematics Designed as an evolution of the ultimate Enduro bike, the new Mega V4 has been fully reimagined for 2021 to offer optimised sizing/fit, enhanced Geometry & suspension kinematics on a brand new Aluminium chassis. Most importantly you can now fit a water bottle inside the main front triangle! Frame Construction: The new Alloy Mega features a full custom triple butted hydro-formed 6061-T6 Aluminium tube set & forged parts. It is available for 27.5” or 29” wheel sizes. These are two totally different, compromise free frames that were designed & 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 & slacker! Our 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 & descending capabilities. Suspension Design: To step-change the Mega's suspension design, Nukeproof went back to the drawing board & started afresh. They redesigned the Mega 4 bar horst linkage to be super supple over small bumps, progressive & supportive throughout the mid stoke for support when pedalling, cornering & 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 & most technical terrain on the way back down.

Sizes: Small through to XX-Large with evenly spaced jumps between each. Lower, longer, steeper & slacker! Our 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 & descending capabilities. Suspension Design: To step-change the Mega's suspension design, Nukeproof went back to the drawing board & started afresh. They redesigned the Mega 4 bar horst linkage to be super supple over small bumps, progressive & supportive throughout the mid stoke for support when pedalling, cornering & 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 & most technical terrain on the way back down.

Nukeproof Mega 275 Alloy Mountain Bike Frame The Mega 275 Alloy Frame features an Enduro World Series proven design that was optimised in partnership with Sam Hill. This full-suspension pro race frame is also equipped with Rock Shox Super Deluxe Ultimate RCT rear shock that's custom tuned to ensure the greatest performance anywhere. &, with tyre clearance for 2.6" tyres, an ISCG05 chainguide mount, internal cable routing, Boost 148mm rear spacing & Enduro bearings throughout, this frame is prepared for everything the mountain throws your way. Introducing the All-New Mega V4: Born Through Evolution, Not Revolution The Nukeproof Mega: an “enduro bike” that was ahead of its time. Originally developed & later named after the race it was designed for on the infamous trails of Alp D' Huez
- the Megavalanche. Multiple Enduro World Series (EWS) Victories To date the Mega platform is one of the most highly decorated race bikes on the market: with the 2017, 2018 (x 2) & 2019 Enduro World Series Titles; a Downhill World Championship top 10 & a Silver Medal at the 4x World Championship to its name. (As well as a host of other national & international victories & titles!) Refined & Optimised for World Class Performance Since 2009 the Nukeproof Mega has been constant path of development to meet the evolving demands of Nukeproof's riders & customers alike. Their team are relentlessly striving for improvements & with each generation the Mega has been chiselled & 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 & refine in order to give their athletes & riders the best possible chance of standing on top of the podium. enhanced Geometry & Suspension Kinematics Designed as an evolution of the ultimate Enduro bike, the new Mega V4 has been fully reimagined for 2021 to offer optimised sizing/fit, enhanced Geometry & suspension kinematics on a brand new Aluminium chassis. Most importantly you can now fit a water bottle inside the main front triangle! Frame Construction: The new Alloy Mega features a full custom triple butted hydro-formed 6061-T6 Aluminium tube set & forged parts. It is available for 27.5” or 29” wheel sizes. These are two totally different, compromise free frames that were designed & 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.
