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.

Nukeproof Mega 275C RS | 180/165 mm | 14.54 kg | € 5,299

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.

Beautiful finish
The grey paint job of the Mega won over all of our test riders – less so the number 1 on the top tube.
Super quiet
The Mega 275C doesn’t make a sound in rough terrain and always remains very quiet. There’s nothing that rattles on the bike and that’s how it should be!
Carbon front, aluminium rear
The Mega 275C features a carbon front triangle paired with an aluminium rear linkage. There’s nothing to fault here in terms of function.

Very sensitive
The rear suspension of the Nukeproof Mega 275C feels very defined yet super sensitive – excellent!
Nukeproof have taken our previous criticism to heart and for 2020 have specced the bike with a pair of SRAM CODE RSC brakes instead of the CODE R. They are even easier to modulate and feel higher-quality in general.

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.

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.

Intended Use










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
