Nukeproof Reactor 275 Alloy Frame

This full suspension mountain bike (MTB) frame features a tough 6061 aluminium construction that's been put through a hydroforming and triple-butting process to ensure maximum strength and durability, as you dominate your way around the mountain. Also benefitting from a dependable RockShox Super Deluxe Ultimate RCT rear shock, this model delivers smooth and consistent rear end suspension performance, whatever the trail conditions.

Whether you're shredding your favourite local trails with your riding buddies or attacking some technical routes on your own, this full suspension MTB frame is engineered for performance. Coming complete with 148x12mm Boost rear hub spacing and internal cable routing, this is a perfect choice of upgrade for handling the demands modern MTB 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.

Triple-Butted 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, Nukeproof 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.
