Description

Nukeproof Reactor 290 Elite Carbon Bike (SLX)

Taking its name from the original Nukeproof Reactor trail bike back in 1996, this full carbon framed 29er has rocketed up to date with only the greatest technological advancements included within its build. With only latest and greatest components on the market in its arsenal aboard an immensely versatile and adaptable geometry frame design, this ride is destined to be your go-anywhere trail companion.

Ultra-Strong and Lightweight Carbon Fibre Construction

This ultimate aggressive high-performance 29er trail bike features a full carbon frame construction and modern geometry to tame any mountain with its robust, stable and strong adventure potential. Engineered with a UD woven carbon fibre frameset, it gives you the most essential confidence in its ability on even the most technical descents and the greatest traction and comfort for demanding climbs. These capabilities are thanks to the frame’s ultra-strong Monocoque carbon tube set and carbon seat stays, which ensure consistent and reactive handling with a low unsprung weight. This low weight and modern geometry makes the suspension as active and stable as possible and smooths out the roughest line-choices for immense speed and control.

Shimano SLX 1×12 Drivetrain and Fox Suspension Components

Equipped with the latest drivetrain and suspension technology and a superb Nukeproof finishing kit to complete its build. This ride is a top performer that’s ready for soaring the highest peaks and descending the steepest chutes. And, to ensure this intention is a reality, Nukeproof has kitted it out with a Shimano SLX 1×12 drivetrain, Nukeproof’s “flip-chip” adjustable suspension geometry, Fox 36 Float suspension forks and a Float DPX2 rear shock, DT Swiss M1900 Spline wheels and 4-Pot SLX disc brakes from Shimano. This ride is born to blast descents, shred trails and boost roots, and its exceptionally stable pedalling platform easily gets you back up to the top again for another run back down.

Technologies:

  • 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.

Easy Assembly

When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box.

Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

  • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
  • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
  • All bikes for worldwide delivery outside the EU will be delivered in small boxes.

Bike Sizing Guide

Choosing the bike size depends on the type of bike, your height, your riding style, and your preference. A correct fitting bike will be more comfortable, more efficient and more fun to ride. This bike size guide gives our customers general advice on choosing the right size. It is a guide only and we always recommend visiting one of our stores or contacting one of our experts from our contact us page.

To get started, think about your style of riding, measure your height and use the links above for sizing on relevant bike types.

 

Measure your height

To find the correct sized bike you will need to measure your height and your inside leg. For your height, stand against a wall and mark the wall with a pencil so it's level with the top of your head. Then measure from the ground up to the mark (having someone to help might make this easier). For your inside leg measurement, stand against a wall and using a book hold it in between your legs into your groin and make sure it's flat against the wall. Measure the height from the book to the floor. (Again it might be easier to get a friend to help). If your height is on the cusp of the size range, your reach is often the deciding factor in which size to go for. To find out if you have short or long reach you will need to measure your ape index. This is your arm span minus your height. If you have a positive ape index then go for the larger size, or if you have a negative ape index go for a smaller size.

 

The type of bike

What type of bike you choose will affect the bike size you buy. The type or style of riding that you do will also affect which size you need. For example a mountain biker that wants to ride more aggressively and would like a more manoeuvrable bike may prefer a size smaller than they would normally take. Likewise a cross country racer that is looking for a flatter and speedier mountain bike may prefer a size larger than they would normally take. There is no definitive right or wrong size, it all comes down to personal preference and what feels comfortable. The different types of bikes are all explained within our buying guides.

 

How are bikes measured?

Bikes are measured by their seat tube length. This measurement is normally from the centre of the bottom bracket (BB) or the centre of the bolt that attached the crank arms. This differs by brand, some measure to the top of where the top tube meets the seat tube, or even the centre of the top tube. Mountain bikes are either measured in inches or descriptive sizes (small, medium etc). Road bikes are in centimetres or descriptive sizes where as Hybrid bikes can be any one of the three. Bikes also get longer as they go up in size (relative to the frame size) but different brands can be inherently longer or shorter than others.

 

Stand over height

Stand over height is how tall the frame is from the ground. Stand over height measurements are to the top of the top-tube. Ideally you want at least 2cm of clearance between you and the frame. In theory your stand over height is your leg measurement minus 2cm. It it worth measuring your inside leg with your shoes on so you can establish your stand over height. Should you need to jump off the saddle quickly, the clearance between you and the frame will prevent any injuries.
