The Nukeproof Mega 275C RS didn’t only secure the Best Value Tip in our big enduro bike group test last year, it also helped Sam Hill claim his third overall title in the Enduro World Series. This year it’ll have to defend its title, going up against its sibling, the Mega 290C and many other bikes besides in our group test.

At first glance, the Nukeproof Mega 275C RS seems to be stepping into the ring virtually unchanged. But look more closely and you’ll find a couple of minor updates: it’s been given a new paint job and the rear linkage has been upgraded with higher quality Enduro bearings. Apart from that, it now comes standard with protective frame tape covering all critical spots. The spec has also been tweaked. You still get a red RockShox Lyrik fork, although this is the Ultimate model offering 170 mm travel instead of the RC2. The fork is combined with a Super Deluxe shock, while shifting is taken care of by a SRAM X01 drivetrain and Michelin supply the grippy Wild Enduro tires. For 2020, the tires come fitted on a set of Mavic Deemax DH wheels. Nukeproof have fixed the small criticism we had last year and now spec the bike with a pair of SRAM CODE RSC brakes instead of the CODE R model. Because of the position of the shock in the front triangle, you’ll have to mount your water bottle under the downtube and the price of the Mega 275C RS has gone up by € 500 from € 4,799 to € 5,299. Nukeproof justify the price increase based on both the improved componentry and the effects of Brexit negotiations resulting in worse exchange rates for British companies.

Geometry and size of the Nukeproof
Above all, the Nukeproof Mega 275C is extremely balanced, which can be attributed
to the geometry. The reach isn’t radical and the chainstays are relatively long for a bike with 27.5” wheels. This positions the rider very centrally between the wheels. The remaining geometry figures are also spot on and thanks to the moderate seat tube length there is enough room for a 170 mm dropper post.
|Seat tube||381 mm||420 mm||420 mm||458 mm||508 mm|
|Top tube||560 mm||586 mm||603 mm||623 mm||669 mm|

The Nukeproof Mega 275C RS on the trail
The pedalling position on the Mega 275C is central, upright and very comfortable on the climbs. The rear suspension effectively suppresses pedal bob, meaning it only makes sense to activate the shock’s climb switch on long climbs with smooth surfaces. As inconspicuous as it is on the climbs, so it is on the descends – in the most positive sense of the word. The Mega 275C is synonymous with balance, handling brilliantly on every kind of terrain. This all comes down to the excellent weight distribution that results from the rather long (for a 27.5″ bike) 435 mm chainstays.
The Mega 275C makes it possible to stay in control while going full speed and drifting Sam Hill style.
This keeps you centred on the bike without having to shift your weight around too much, generating equal amounts of grip on both wheels and allowing you to focus on riding the trail. The rear suspension responds sensitively while offering lots of mid-stroke support and plenty of progression towards the end, making the travel feel bottomless. The Mega 275C is an easy bike to ride fast without demanding a lot of energy from the rider, yet the handling remains very agile, allowing you to change direction with precision and ease. The 170 mm RockShox Reverb dropper post guarantees maximum freedom of movement and increases your feeling of confidence on steep terrain.
The Mega 275C is still an excellent bike, the only problem is: the 29er is even better!
How does the Nukeproof Mega compare to the competition?
The best bike to compare it to is its bigger wheeled sibling, the Nukeproof Mega 290C. Sadly, the Mega 275C isn’t able to keep up. Although it might be marginally more agile in tight sections, it doesn’t roll over obstacles as easily and the 29er instils you with significantly more confidence. Most riders will be better advised to go with the 29er unless you’re specifically looking for a very agile bike and want the smaller wheels – in which case you might rather want to go for Nukeproof’s new Reactor anyway.
Tuning tip: none
The Nukeproof Mega 275C RS performs well on every kind of terrain thanks to its balanced handling, excellent suspension and carefully considered spec. It always remains predictable and delivers EWS performance for the masses. The only problem facing the 275 is the fact that that you can now get pretty much the same bike with 29″ wheels, leaving this smaller wheeled version behind.
- excellent cornering abilities
- brilliant suspension
- carefully considered spec at a fair price
- no room for a water bottle

This scale indicates how efficiently the bike climbs. It refers to both simple and technical climbs. Along with the suspension, the riding position and the weight of the bike all play a crucial role.↩
How does the bike ride and descend? How spritely is the bike, how agile is it through corners, how much fun is it in tight sections and how quickly can it change direction?↩
Is the bike stable at high speeds? Is it easy to stay in control in demanding terrain? How composed is it on rough trails? Stability is a combination of balanced geometry, good suspension and the right spec.↩
This is all about how balanced the bike is and particularly about how well it corners. Balanced bikes require little physical effort from the rider and are very predictable. If a bike is unbalanced, the rider has to work hard to weight the front wheel to generate enough grip. However, experienced riders can have a lot of fun even with unbalanced bikes.↩
How sensitive is the suspension over small bumps? Can it absorb hard impacts and does it soak up repeated hits? Plush suspension not only provides comfort and makes a bike more capable, but it also generates traction. The rating includes the fork and the rear suspension.↩
This aspect mainly comes down to the suspension. How much pop does it have, does it suck up the rider’s input or is it supportive, and how agile and direct is the bike?↩
We don’t calculate value for money in an excel spreadsheet or based on how high-end a bike is specced. We are more concerned with how a bike performs on the trail and how the bike benefits the rider. What good are the best components if the bike doesn’t perform well on the trail? Expensive bikes with a lower-end spec can offer very good value for money – provided they excel where it matters. Just as supposedly cheap bikes with good components can get a bad rating if they don’t deliver on the trail.↩
No, it’s not about racing, it’s about efficiency. Fast, fleet-footed and efficient – those who want to speed along flowy singletrack and gravel roads need a defined and spritely bike that accelerates with ease and efficiency. Nevertheless, reliable components are important too. We interpret XC more like the Americans do: big back-country rides instead of a marathon or XC World Cup with the ultimate in lightweight construction! Uphill-downhill ratio: 80:30 (not everything has to be 100%!)↩
...also known as mountain biking. Classic singletrack with roots, rocks and ledges – sometimes flowy, sometimes rough. For this, you need a bike with good all-round qualities, whether climbing or descending. Uphill-downhill ratio: 50:50↩
Even more extreme and challenging compared to Trail riding, riddled with every kind of obstacle: jumps, gaps, nasty rock gardens, ruts and roots. For this, you need (race)proven equipment that forgives mistakes and wouldn’t look out of place on a stage of the Enduro World Series. Climbing is just a means to an end. Uphill-downhill ratio: 30:70↩
Strictly speaking, a 200 mm travel downhill bike is the best choice for merciless tracks with big jumps, drops and the roughest terrain. Those would be the black or double-black-diamond tracks in a bike park. But as some of the EWS pros (including Sam Hill) have proven, it’s the riding skills and not the bike that define what you can ride with it. Climbing? On foot or with a shuttle, please! Uphill-downhill ratio: 10:90↩
