Boasting a rock-solid 6061 aluminium build, this trail-ready mountain bike (MTB) frame is engineered to endure the most demanding of terrain conditions. Thanks to its hydroforming and triple-butting process, it offers extra durability as you charge from trail to trail.
This trail-ready mountain bike (MTB) frame features a rock-solid 6061 aluminium build, which makes it more than capable of enduring the most demanding of terrain conditions. Nukeproof has also put this model through a hydroforming and triple-butting process for extra durability as you charge from trail to trail. Another highlight is its RockShox Super Deluxe Ultimate RCT rear shock, which gives you increased tuneability and control from your rear end suspension's performance. This makes it ideal for blasting across rock gardens, tree roots and whatever the trail has to throw at you on your ride. Benefitting from updated geometry, internal cable routing and 148x12mm rear hub spacing, this full-suspension MTB frame is fully equipped for the rigours of modern trail riding.
From 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.
### Full Suspension Alloy MTB Frame
The Alloy Reactor features a custom triple butted hydro-formed tube set and carbon seat stays, which help reduce the overall weight of the frameset. Critically this reduces the unsprung weight; making the suspension as active as possible.
The Reactor 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”?
### Adjustable Geometry
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.
### Suspension Design
To ensure the bike could climb as well as it descends, we designed the four 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.
