Nukeproof’s Trail Bike – the Reactor

Based on how far back your mountain bike reputation information moves, the Nukeproof Reactor rap might be familiar. It was initially employed for a light weight aluminum hardtail within 1996, when Nukeproof was continually grounded within Grand Rapids, Michigan. Almost twenty five years further along the product name has resurfaced, though this time it is being applied to a full suspension, aggressive trail bike that is readily available with either 27.5″ or maybe 29″ wheels.

The 27.5″ Reactor has 140mm of back travel and also a 150mm fork, and the 29″ edition has 130mm of back travel and also a 140mm fork. There is in addition an RS model for both wheel sizes of the shoes, and that views the fork traveling bumped in place by ten millimeters.

Nukeproof Reactor Details

• Wheelsize: 29″ or perhaps 27.5″
• Aluminum or perhaps carbon frame choices • Travel: 130 (29″) or 140 (27.5″)
• 2.6″ tire clearance
• twelve x 148mm rear spacing
• Threaded BB
• Price: £2,729 – £5,399

In addition to the 2 wheel size choices, you will find carbon and aluminum framed models. This is Nukeproof Bikes very first complete carbon frame – their earlier carbon bikes worn alloy swingarms. Today, including the aluminum bike becomes carbon seatstays to drop some weight.

Complete bike rates vary from £2,750 for the lightweight aluminum Comp design up to £5,400 for the carbon RS edition. There is a good number of build kit choices, with 2 total aluminum models and 4 carbon versions, along the choice to go the frame only route.

The Reactor is anticipated to be for sale by late October.

Frame Details

Space for a water container inside the forward triangle? Check. Threaded bottom bracket? Check. All those 2 details that are important are looked after, then Nukeproof similarly equipped the Reactor with an ample downtube protector in order to ward of flying other debris and rocks, along with plenty of space to suit 2.6″ tires, and to operate something small and have additional mud clearance.

The brake and derailleur housing are internally routed from the front triangle, however emerges just before the bottom part bracket and stays externally routed on the swingarm. That under-the-BB routing is the effort of contention for a few riders, though it’s reasonably unusual to encounter any problems with squized or maybe smashed casing – the chainring or crankarms are much more prone to get to an obstacle first. On the subject of smashing into immovable items, the Reactor also has ISCG five tabs for chain guidebook or bash guard mounting.


Regardless of the controls sizing, the Reactor has a sixty six or maybe a 65.5 degree head angle based on the position of the flip chip that is discovered on the seatstay. Flipping the the chip in the steeper’ Trail’ to the’ Rail’ place in addition drops the bottom part bracket level by 6mm, and also slackens the hold tubing perspective to 75 degrees.

On the RS versions, the greater fork slackens the top angle to both 65.5 or maybe 65 degrees, as well as the seat angle drops to both 75.1 or perhaps 74.6 degrees. The seat angle is not as sheer as what is rapidly becoming the majority – we will see what that translates to out on the trail when we get a Reactor in for feedback.

Reach numbers range through 451mm to 514mm with the 29″ model, and then 425mm to 516mm for that 27.5″ choice.

Suspension Design

The Reactor’s Horst Link suspension format is akin to whats located on the Nukeproof Mega, although kinematics are changed to fit the Reactor’s slightly much more pedaling oriented focus. Anti-squat sits at ninety two % during the 32/50 gear ratio, though it falls off fairly quickly as the bike goes through the travel of its to be able to enable the suspension to your workplace unimpeded on rougher surface.

The Reactor has a twenty one % leverage ratio shift, which is also a little above the Mega. Which was completed to be able to boost the quantity of end-stroke ramp and mid-stroke support up – Nukeproof count on this particular bike to be ridden tough, and do not wish riders to end up blowing through the reasonable level of traveling much too fast.


Nukeproof’s components spec for the Reactor create its’ get rowdy’ motives crystal clear. All bikes have a piggyback shock from either Rockshox or Fox, along with a 2.5″ Maxxis Assegai or 2.4″ Minion DHRII tire combination. A 200mm rotor and strong brakes can also be regular on most models also – this is not a bike which was created for casual cruising.
