Nukeproof Reactor 275 Pro Alloy Mountain Bike 2022 Rosso Red

Season:2022

Brand:Nukeproof

Code:NPREA275P

From concept through to design, the Kinematics, the geometry and specification; the Reactor is designed from the ground up to be the ultimate aggressive trail bike. It is at home on technical climbs, but happiest when thrashing the most technical trails you can point it at.

The Reactor frame is crafted from hydroformed triple butted 6061 aluminum. To reduce unsprung mass the seatstays on the Reactor are molded from carbon fibre. All frames are available for 27.5” or 29” wheel sizes. Each wheelsize is based on two totally different, compromise free frames. Each were designed and developed at the same time and optimized around each wheel size.

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 maximize 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.

Size Guides are a great way to help you find the right bike, but we always recommend visiting our store to view and sit on the bike in person where possible or speaking to our advice team.

This Size Guide is based on an average build, if you have shorter arms or longer legs for example you will need to consider this when purchasing a bike. If you are between sizes, we always recommend sizing down as a smaller bike can be made bigger with adjustments. Stem length, Saddle height, Handlebar width and even Crank length can be changed to achieve the ideal riding position. See here for our general bike sizing guide.
