From concept to kinematics, geometry to spec, the Nukeproof Reactor was built from the ground up to be the ultimate aggressive trail bike. It climbs with precision but truly comes alive when you’re charging technical trails. Constructed from a hydroformed and butted 6061 T6 aluminium alloy, with carbon fibre seat stays to reduce unsprung mass and optimise lateral stiffness. The Reactor delivers the perfect blend of low weight, strength, and stiffness. Made for long days in the saddle, it’s your go-anywhere trail weapon—ready for epic adventures where a 1,000m climb leads to a 1,000m descent. Whatever the trail throws at you, the Reactor 290 Alloy is built to take it on.
Features
Seamless trail shredding
Every detail of the Nukeproof Reactor is engineered to make life on and off the trail seamless. With rider focused practicality at its core, it combines performance with easy service. The front triangle accepts a full size 750 ml water bottle and an accessory mount under the top tube carries tools or spares, ideal for long self supported rides. Generous mud clearance for tyres up to 2.6 inches ensures reliability in harsh conditions, while MAX bearings throughout the frame deliver lasting smoothness and durability. Servicing is straightforward thanks to accessible hardware, sensible Allen key sizes and laser etched torque markings, complemented by tube in tube internal cable routing for a clean and rattle free setup. 3D contoured rubber guards protect key areas from impacts and chain noise. Thoughtfully engineered and trail proven, the Reactor is built to perform ride after ride.
Adaptability and frame construction
The Reactor Alloy balances toughness, precision and performance. It uses a 6061 T6 aluminium front triangle and chainstays for strength and reliability in aggressive trail riding, with a carbon fibre seatstay to fine tune responsiveness and vertical compliance. This hybrid layout gives a lively yet controlled feel on the trail, stiff and direct when pushin
