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
To optimise the weight, strength and stiffness, the Reactor Carbon frame features a full UD woven carbon fibre frameset (Including chain and seat stays). It is available for 27.5” or 29” wheel sizes. These are two totally different, compromise free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size.
Speed or play: which do you value more? The manoeuvrability of 27.5” or the raw speed of a 29”?
All Reactor frames feature a “flip chip” to adjust the geometry from “Trail” to “Rail mode”.
Trail – As the name suggests, this setting is best suited for trail riding. It is for riders who get as much enjoyment from the climb as the descents.
Rail – The Rail setting turns the Reactor into a corner shredder, dropping the bottom bracket 6mm and slackening the head angle by half a degree. It is there to maximise the descending capabilities.
To ensure the bike could climb as well as it descends, we designed the 4 bar horst linkage to have higher levels of anti-squat for climbing gears but lower levels when you drop down the cassette. This means that the bike can behave itself on the climbs but when you get it up to speed, it turns into a trail hooligan. The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.
