Nukeproof Reactor 290 Comp Alloy Bike Mountain Bike £1669.98 Delivered @ Chain Reaction Cycles

Product descriptionFrom concept through to design, the Kinematics, the geometry and specification; the Reactor is designed from the ground up to be the ultimate aggressive trail bike. It is at home on technical climbs, but happiest when thrashing the most technical trails you can point it at.

To optimise the weight, strength and stiffness, the Reactor Carbon frame features a full UD woven carbon fibre frameset (Including chain and seat stays). It is available for 27.5” or 29” wheel sizes. These are two totally different, compromise-free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size.

Speed or play: which do you value more? The manoeuvrability of 27.5” or the raw speed of a 29”?

All Reactor frames feature a “flip chip” to adjust the geometry from “Trail” to “Rail mode”.

Trail – As the name suggests, this setting is best suited for trail riding. It is for riders who get as much enjoyment from the climb as the descents.

Rail - The Rail setting turns the Reactor into a corner shredder, dropping the bottom bracket 6mm and slackening the head angle by half a degree. It is there to maximise the descending capabilities.

To ensure the bike could climb as well as it descends, Nukeproof designed the 4 bar horst linkage to have higher levels of anti-squat for climbing gears but lower levels when you drop down the cassette. This means that the bike can behave itself on the climbs but when you get it up to speed, it turns into a trail hooligan. The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.

Please Note: Due to severe delays in the bicycle supply chain, Nukeproof has been forced to make some alterations to the specification of the component parts supplied with this bicycle. As a result, the specification may differ from those shown in the images. Please refer to the specification table above for accurate information.

Please note that due to ongoing issues in the global bike supply chain, manufacturers may substitute certain component items due to availability. In this situation, they will be replaced with the same quality or better performing parts.

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 and plastic pedals 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 balance 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. Again, the exception is balance 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.
