A Fast, Agile, and Capable Trail Bike for Serious Riders
The 2027 Nukeproof Reactor Alloy Pro in Nukeproof Yellow is built for riders who want a lively, responsive, and highly capable full‑suspension trail bike. Sitting above the Reactor Alloy Comp, the Pro model introduces upgraded suspension, refined components, and a more aggressive ride feel that encourages speed and precision on technical terrain. It’s designed for riders who push hard on climbs, attack descents, and want a bike that feels sharp, controlled, and ready for demanding trail riding.
Lightweight Alloy Frame with Progressive Reactor Geometry
The Reactor Alloy Pro uses a lightweight aluminium frame engineered around Nukeproof’s progressive Reactor geometry, giving riders a centred, confident position that balances climbing efficiency with descending stability. The frame’s proportions make the bike feel agile in tight corners while remaining composed at speed, offering the perfect blend of responsiveness and control. Its durable construction ensures it can handle aggressive riding, while the Nukeproof Yellow finish gives the bike a bold, unmistakable identity on the trail.
Premium Suspension for Precision and Control
A major upgrade on the Pro model is its enhanced suspension package, offering improved damping, better support, and more control on rough terrain compared to the Alloy Comp. The combination of a responsive RockShox Super Deluxe Select+ Air rear shock and a high‑performance RockShox Lyrik Select + fork helps riders maintain traction on roots, rocks, and uneven surfaces, giving the bike a smooth, planted feel even when riding at speed. This suspension setup is designed for riders who want a bike that reacts instantly to input and stays composed on demanding trails.
Wide‑Range Drivetrain for Technical Trail Versatility
The Reactor Alloy Pro features a wide‑range SRAM Eagle 90 drivetrain that helps riders tackle steep climbs, fast flats, and technical descents with confidence. The gearing is chosen to be intuitive and reliable, allowing riders to maintain a comfortable cadence across varied terrain. Whether powering up climbs or accelerating out of corners, the drivetrain supports a fast, efficient riding style.
Hydraulic Disc Brakes for Confident, Controlled Stopping Power
Reliable SRAM Maven Base hydraulic disc brakes give the Reactor Alloy Pro strong, consistent stopping power in all conditions, from dry hardpack to wet and muddy trails. Their predictable feel helps riders stay in control on steep descents and navigate technical sections with precision, making them an essential part of the bike’s high‑performance trail capability.
Fast‑Rolling Wheels and Trail‑Focused Tyres
The DT Swiss M1900 wheels and Schwalbe tyres are chosen to give the Reactor Alloy Pro a fast, stable feel on mixed terrain. The tyres offer reassuring grip without adding unnecessary weight, helping riders maintain momentum and control as they push harder on technical trails. Whether on flowing singletrack, rocky climbs, or fast descents, the bike feels lively, predictable, and ready for aggressive riding.
Nukeproof Yellow: Bold, Modern, and Unmistakably Reactor
Finished in Nukeproof Yellow, the Reactor Alloy Pro has a striking, high‑energy aesthetic that reflects its premium status. It’s clean, sharp, and unmistakably Nukeproof — a bike that looks fast even when standing still.
