2026 Nukeproof Reactor - Aluminium Trail Brute
The Reactor Alloy Pro is Nukeproof’s aggressive trail bike — fast on descents, efficient on the climbs, and built to thrive on long days where terrain constantly changes. With 140 mm of rear travel, a 150 mm fork, and geometry designed to balance agility and stability, the Reactor is the “go-anywhere” platform for riders who want one bike that can do it all.
Constructed from hydroformed 6061-T6 aluminium with UD carbon seatstays, the Reactor delivers a blend of strength, stiffness and low unsprung mass. The result is precise handling, excellent tracking and suspension performance that stays active whether you’re climbing technical singletrack or pushing hard into rough, fast trails.
Ex-Staff/Demo with upgrades! Set to Mullet configuration.
