Nukeproof Reactor Alloy Pro 2026
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. All frames feature a flip chip to adjust the geometry from a trail to a rail setting.
The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.
