Nukeproof Mega 290 Carbon Frame (EXT Shock)

Nukeproof Mega 290 Carbon Frame (EXT Shock)

The ideal frame for enduro racing across the roughest terrain, this enduro-focused mountain bike (MTB) frame features an ultra-strong carbon fibre construction that delivers maximum stiffness and strength, without adding any unnecessary excess grams to your ride. It is also equipped with an ultra-responsive EXT STORIA LOK V3 Coil rear shock that offers excellent rear wheel tracking and bump swallowing performance as you charge across rock gardens, tree roots and trail debris.

Agile and responsive, this version benefits from race-ready geometry with internally piped cable routing, which provides smooth handling as well as a clean finish. Ideal for completing your enduro bike build, a final highlight is its 148x12mm Boost rear hub spacing that ensures strong and stiff control as you race for the podium.

For over 12 years, Nukeproof’s best-selling model; the Mega has been racking up awards on Enduro stages and in the press around the world. With four Enduro World Series titles to its name, the Mega has become an icon that is synonymous with racing.

Since 2009, the Nukeproof Mega has been on a constant development to meet the demands of Nukeproof’s riders and customers alike. As a result, the Mega Carbon V4 frame is available for 27.5”, 29” or new Mixed (Front 29”/Rear 27.5” wheel sizes) wheel set ups, with each frame design tailored around each wheel size.

Race-Ready Carbon MTB Frame

To optimise the weight, strength and stiffness, the Mega Carbon frame features a T700/800 UD woven carbon fibre frameset (front and rear triangle). The carbon swingarms helps reduce the unsprung weight on the rear of the bike, improving suspension performance. All forged parts are made from 6061-T6 aluminium.

EXT STORIA LOK V3 Rear Shock

The STORIA LOK V3 offers the revolutionary LOK Technology that allows a complete compression separate lock-out system, now totally renewed with a new design, a more progressive opening, and a totally silent working.

In order to allow every rider to use a softer spring rate and increase bike traction and handling, EXT engineers have imported from ARMA the hydralic bottom out system named HBC (Hydraulic Bottom-out Control), capable to develop more than 50% of hydraulic force only on the last part of the stroke, allowing riders to avoid any kind of bottom-out issues.

This technology allows the use of thinner bottom-out bumpers, increasing the amount of useful travel.

The STORIA V3 is also designed to serve riders who want maximum performance of a pedal-platform equipped shock, with a great support on the last millimeters of bike rear travel, with the great performance of a coilover shock.

Nukeproof’s Ultimate Enduro Race Bike

After winning four Enduro World Series Titles in three years the V4 design is an evolution of Nukeproof’s ultimate enduro bike. At the heart of the frame is the brand’s revised suspension Kinematic, designed to be more subtle off the top, whilst remaining progressive and predictable. Anti-Squat is used to create an effective pedalling bike that can be thrashed through technical terrain. The useable SAG range is also widened to allow riders to tune the suspension to the trails. Other key features include:

• All new UD Carbon chassis
• Improved suspension kinematics
• Tube-In-Tube design for easy cable installation
• All new geometry
• Optimised sizing/fit – Small to Large
• SRAM UDH
• Room for a 750ml water bottle inside the main front triangle
• EXT STORIA LOK V3 Coil Rear Shock

The updated Mega frame geometry features a dynamic saddle offset, which is designed to optimise seated rider weight distribution on each frame size. This is achieved through seat angles that are bespoke to each frame size. In addition, the actual seat tube is designed to be shorter overall with a bigger maximum insert depth to allow for a longer dropper post if required.
