Although it takes its name from the original 1996 Nukeproof Reactor trail frame, a lot has changed in the last 23 years and it now features an all-new trail focussed platform.
This innovative 275 Pro Carbon model is equipped with the latest tech and spec, including a full SRAM GX Eagle 12-Speed drivetrain, "flip-chip" adjustable suspension geometry, high-end RockShox suspension and a superb Horizon finishing kit from Nukeproof. This advanced build ensures you're always at one with your momentum, control and gives you the ability to send it further and with more confidence than ever before.
Designed from the ground up to provide the ultimate in aggressive trail bike performance, this MTB-legend features advanced suspension kinematics, modern geometry and a unique design to stand out from the crowd. Built to blast up the steepest and most technical climbs with ease and ensures you are the supreme-commander of this rig on the descents, this bike was born to thrash technical trails with more style than ever before.
With a full UD woven carbon fibre construction at its core, this Reactor model is engineered to provide the best strength and stiffness at a low weight. Optimised to ensure the greatest manoeuvrability and control, this 275 Pro design floats across the most demanding terrain with market-leading trail-smoothing performance and confidence-inspiring aggression.
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.

Getting the Right Fit
At Wiggle we measure each of our bikes to build accurate size charts for our customers. Our qualified team of mechanics then individually check each order, against measurements supplied by you, to ensure the size chosen is correct. Another reason you can have complete confidence when buying a bike from Wiggle!
If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
