  • Nukeproof Mega 290 Alloy Mountain Bike Frame

    Designed to excel on the toughest enduro and all-mountain runs, the gravity focused specification of this Nukeproof Mega 290 Frame 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. Making the decision to commit to a dedicated 1x drivetrain configuration across all models, its engineers have been able 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 you to fit much stiffer and stronger wheels. All 2019 Nukeproof Mega frames will come with Boost spacing enabling the rider to feel even more confident on the increased capability of the bike.

    Boost Spacing

    With stiffness in mind, Nukeproof took the time to incorporate the very latest Boost 148 rear axle spacing, which means you can include much stiffer and stronger wheels both front and rear. The wider spaced Boost wheels and forks enable 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 Nukeproof's Mega 290 Frame.

    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 updated 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 Mega with its updated ’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.
