After a successful season of racing and testing underneath Sam Hill, Nukeproof's new Mega 275 Carbon is now available for the masses. The bike was originally conceived four years ago, but Nukeproof took their time during the development process, experimenting with different layups in order to achieve the blend of stiffness and light weight that's expected from a carbon frame aimed at taking on the Enduro World Series. The result is a frame that's 320 grams lighter than the aluminum version, a very respectable weight savings, especially considering that that swingarm is still aluminum.
Nukeproof Mega 275 RS Details

• 65° head angle
• 165mm travel, 170mm fork
• Threaded bottom bracket

• Sizes: S, M, L, XL
The Mega 275 Carbon has 165mm of rear travel that's delivered via a Horst Link suspension design, and it now uses metric shock spacing, with wider mounting hardware at the front of the shock compared to the previous alloy version in order to add stiffness and increase its resistance to side loading. The frame is also 1x specific – ditching the front derailleur allowed Nukeproof to stiffen up the bottom bracket area by increasing the space between the main pivot bearings.
The Mega is designed to work well with either an air or coil shock, although all of the stock models come with an air shock. In addition to the switch to Boost spacing, the bike's geometry has been tweaked slightly, with longer head tubes and an increased reach on the large and extra-large sizes.
Fans of aluminum don't need to worry - there are still two aluminum Mega 275 models in the lineup, with the same geometry, Boost spacing, and metric shock as the new carbon version.GeometryFirst Ride
I was able to get in one long lap aboard the Mega 275 Carbon, beginning on Whistler's Top of the World trail and continuing the descent on the rooty, dusty, and always entertaining trails located just outside of the Whistler Bike Park. What struck me most about the bike was how energetic it felt, especially for a 160mm enduro bike. There's a snappiness to its handling that makes it easy to pump through rollers and double up sections of trail when necessary, with plenty of cushion for plowing through the rough stuff. There wasn't much sustained climbing on that initial ride, but on short, punchy ascents the Mega responded well, with crisp acelleration even during hard, out of the saddle efforts.
It's easy to see how the Mega 275 Carbon would do well as a race bike, even if your last name isn't Hill – it manages to feel burly and lively, a combination of traits that should help it shine on a wide variety of terrain. Of course, I would have liked to see room to mount a water bottle inside the front triangle, but at first glance there's not much else to gripe about – the bike is well appointed, with a 170mm RockShox Lyrik RCT3, SRAM Code brakes, and a 12-speed Eagle drivetrain. We'll work on getting one in for a long term review in order to see how it handles a Pacific Northwest fall / winter.
There's no carbon version of the Mega 290 – at least not yet – but the 150mm big wheeler also received slightly updated geometry, along with a 160mm fork up front, Boost spacing, and a metric shock for 2018. There are three complete models, the Mega 290 Comp ($2750 USD), the Pro ($3800), and the top-of-the line Factory model for $4,300.Geometry
