Nukeproof Mega 290 Comp Alloy 29" Mountain Bike 2021 - Trail Full Suspension MTB
For over 10 years, our best-selling model; the Mega has been racking up awards on Enduro stages and in the press around the world. With 4 Enduro World Series titles to its name, the Mega has become an icon that is synonymous with racing. However, we never rest on our laurels and 2021 sees the introduction of the 4th generation Mega.
Since 2009 the Nukeproof Mega has been on a constant development to meet the demands of our riders and customers alike.
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 new carbon swingarms helps reduce the unsprung weight on the rear of the bike. Again, the Mega is available in both 27.5” or 29” wheel sizes, with both frame designs tailored around each wheel size. All forged part are also made from 6061-T6 Aluminium
After winning 4 Enduro World Series Titles in 3 years the all new design is an evolution of our ultimate Enduro bike. At the heart of the frame is all new suspension Kinematics, 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 Carbon chassis
Designed and improved suspension kinematics
Tube In Tube design for easy cable installation
All new Geometry
Optimised sizing/fit - Small to XXL
SRAM UDH
Now fits a 750ml water bottle inside the main front triangle!
The new Mega frame is optimised around the rider and weight distribution. The new geometry features dynamic saddle offset. Seat angles are optimised for each frame size and the seat tube itself is designed to take a longer dropper post if required.
Occasionally, without notice, manufacturers change product design and/or specifications.
