  • Nukeproof Reactor 290 Carbon Frame

    This mountain bike (MTB) frame features an ultra-strong T700/800 monocoque carbon fibre build for excellent stiffness and durability, without weighing down your ride with unnecessary excess grams. Nukeproof has also kitted out this model with a Factory Series Fox Float X rear shock, which delivers smooth and consistent rear end suspension performance, as you charge across rock gardens, tree roots and debris. Another highlight is its updated geometry with internal cable routing that allows you to enjoy trail-ready handling and control with a clean, sleek finish. Coming complete with 148x12mm Boost rear hub spacing for increased stiffness and strength, this is an ideal choice of upgrade for completing your full suspension MTB bike build.

    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 Carbon MTB Frame

    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”?

    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.
