Nukeproof  Reactor 290 ST Factory Depressed Oubergine

Nukeproof Reactor 290 ST Factory Depressed Oubergine

Crosscountry/backcountry/upcountry/downcountry: However you define it, the Reactor ST does it all and everything in between! It just might be the most versatile bike we have ever made.

The Nukeproof Reactor 290 ST; a limited edition lightweight, short travel version of the Reactor that is designed to tackle serious miles efficiently and comfortably, for all day fun in the saddle.

With a 130mm fork combined with 125mm of rear suspension, the Reactor ST combines the best of an enduro bike (long, low and slack) with the best of an XC Race bike (lightweight spec and efficient suspension) to create a sprightly yet seriously capable machine.

THE DETAIL

Frame Construction:

To optimise the weight, strength and stiffness, the Reactor 290 ST Carbon frame features a full UD woven carbon fibre frameset (Including chain and seat stays).

Adjustable Geometry:

The Reactor ST features a 66.8° (66.3° Low) Headangle atop a 76.3° (75.8° Low) seat angle across a 460mm reach on a Medium frame. We also offer the frame in Large and X-Large sizes. The Reactor ST frames feature the same “flip chip” design as the regular Reactor frame 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 ST into a more aggressive machine, 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 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 ST some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor ST is designed to reward the rider and ensure you get that stoke factor in on any ride.
