Overview

The Nukeproof Reactor Carbon 290 is an aggressive trail and all-mountain bike engineered to climb efficiently and come alive on technical descents. A full UD carbon fibre chassis, including the chainstays and seatstays, blends strength, stiffness and trail-taming compliance for long, demanding rides.

From extended climbs to rough, fast singletrack, the Reactor 290 Carbon balances responsive pedalling with confident control when the trail gets steep.

Availability: Approximate lead time is two weeks, as current inventory ships from the Netherlands.

Adaptable Carbon Construction

The monocoque UD carbon frame is designed around stiffness, strength and comfort, with carbon front and rear triangles. A two-position Trail / Rail flip chip allows geometry adjustment: Trail prioritises a balanced ride, while Rail lowers the bottom bracket and slackens the head angle for more aggressive descending. The rear-triangle chip can also be changed to support a 297 mixed-wheel Rail configuration, as described in the supplied product information.

Optimised Geometry and Suspension

Long, low and slack geometry pairs with a steep effective seat tube angle to support descending confidence and efficient seated climbing. The four-bar Horst-link suspension delivers 140 mm of rear-wheel travel, with sensitivity for traction and mid-stroke support for composed handling over technical terrain.

Trail-Ready Practicality

Frame details include clearance for tyres up to 2.6 inches, space for a 750 ml bottle in the front triangle, an accessory mount beneath the top tube, MAX bearings, internally piped cable routing, laser-etched torque markings and 3D-contoured rubber frame protection.

Size Guide

The Reactor Carbon 290 is offered in S, M, L, XL and XXL. Choose a size using your height, inseam, preferred riding position and the frame measurements above; rider-height ranges were not provided with the source specifications.

Reach (A)Compare the horizontal cockpit length across sizes. Longer reach generally produces a roomier standing riding position.
Stack (B)Use stack alongside reach to understand the height of the front of the bike and your preferred handlebar position.
Standover (P)Check standover clearance against your inseam, particularly if you are between frame sizes.

For riders between sizes, compare the complete geometry chart and your current bike's fit before selecting a frame. Consult the retailer for specific fit guidance if needed.
