Nukeproof Reactor 290 Alloy Pro Eagle90 REA01AS Mountain Bike In Yellow

Brand:Nukeproof

Code:REA01AsSramEagle90

The Nukeproof Reactor is the ultimate aggressive trail bike, designed from the ground up to excel on technical climbs and aggressive descents.

The Reactor frame is crafted from hydroformed triple-butted 6061 aluminium alloy, featuring carbon fibre seat stays to reduce unsprung mass and optimise lateral stiffness. This construction delivers the perfect blend of low weight, strength, and stiffness, ensuring reliability for aggressive trail riding and long days in the saddle.

The Reactor Alloy is built around geometry that balances agility, stability, and all-day efficiency. A long, low, and slack stance adds confidence on descents, while a steep seat tube angle places the rider centrally for precise handling and efficient power transfer on climbs. The four-bar Horst Link platform delivers 140 mm of rear travel, tuned to be supple off the top for traction and comfort, with strong mid-stroke support that keeps the bike lively and responsive in technical terrain.

Adaptability is central to the design. A two-position “Trail or Rail” flip chip lets riders refine geometry and handling. Trail mode provides an efficient, balanced feel for big days, while Rail mode lowers the bottom bracket and relaxes the head angle for more aggressive descending and corner support. The frame is available for 27.5” or 29” wheel sizes, and the 290 Trail or Rail chip in the rear triangle can be switched to a 297 mix wheel Rail chip, ensuring consistent performance across setups.

Features:

  • Hydroformed triple-butted 6061 T6 aluminium alloy front triangle and chainstays.
  • Carbon fibre seat stays to reduce unsprung mass and optimise lateral stiffness.
  • Four-bar Horst Link suspension platform delivering 140 mm of rear travel.
  • Adaptable geometry via the two-position “Trail or Rail” flip chip.
  • Front triangle accepts a full size 750 ml water bottle.
  • Accessory mount under the top tube for tools or spares.
  • Generous mud clearance for tyres up to 6.6cm (2.6").
  • MAX bearings throughout the frame for lasting smoothness and durability.
  • 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.
