Nukeproof Reactor 275 Comp Alloy Bike (SX Eagle)
Back in 1996 the original Reactor was born and set the bar for quality trail riding performance. A lot of time has passed, and a lot of technological advancements have been implemented into this modern re-born steed since then. This all-new Nukeproof Reactor takes aggressive-trail sessioning to new levels of awesome. Equipped with an immensely efficient drivetrain to power you up and down anything while its trail-optimised suspension smooths out even the roughest terrain.
SRAM SX Eagle 1×12 Drivetrain and RockShox Suspension
With top-level design and advanced suspension kinematics at its core, this innovative 275 Comp model features an alloy construction, modern geometry and fantastic components to efficiently get you to your goal. This trail-tamer has a 12-Speed SX Eagle drivetrain from SRAM in its arsenal to soar up the steepest climbs and to put power down on the descents. A trail-focussed suspension combo made-up from RockShox Revelation forks at the front and a Super Deluxe rear shock glides across trail chatter and finds traction in all weathers.
SRAM Guide T Brakes, Sun Ringle Duroc Wheels and Maxxis Tyres
Nukeproof has chosen SRAM Guide T hydraulic disc brakes to keep your speed in check and so you can scrub speed quickly and accurately when needed. To add to this ride’s rolling prowess and traction, this gravity-capable full suspension sled glides aboard robust and lightweight Sun Ringle Duroc wheels wrapped in Maxxis DH-ready tyres to tame the trail and fill you with confidence. This combination works perfectly with Nukeproof’s new trail-optimised suspension platform and gives you the greatest experience out on the mountains and in the forest.

- Flip Chip Adjustable Suspension Geometry: All models of the Reactor feature a “flip-chip”, so that the bike geometry can be easily adjusted from “Trail” to “Rail” mode without having to custom tune your suspension setup. The Trail setting is best suited for pumping and carving your rhythm and style into the mountainside and still caters for rides who love the climb as much as the descent. On the other hand, the Rail setting turns the Reactor into an adrenaline-fuelled gravity tamer. Dropping the bottom bracket height by 6mm and slackening the head angle by half a degree, these changes give this Reactor greater stability and control when the trail leans downhill towards vertical.
- Nukeproof 4-Bar Horst Linkage Suspension Design: Ensuring the bike can climb as well as it descends, Nukeproof focussed on fine-tuning their 4-Bar Horst linkage suspension setup to give higher levels of anti-squat performance when higher up the cassette in the climbing gears, but also to deliver greater trail-gobbling performance when you drop down the cassette and begin descending the mountain. This means that the bike behaves itself on the climbs and grips with unprecedented traction and efficiency when making your way back towards sea-level. When you get it up to speed and drop a few gears to carry momentum, this bike turns into a trail hooligan and helps you carve the trail with style. The combination of low anti-squat and progressive suspension-rate give it the ultimate in small bump compliance (removes rough trail and root chatter) with good mid-stroke support for cornering/pumping and end stroke progression for aggressive riding. With balanced anti-rise suspension performance, the Reactor provides some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure stability and traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.
