A demon on the downhills.

Are you looking for an equally playful and aggressive trail bike? Get yourself the Nukeproof Reactor Carbon 290! It'll get you all the way up the hill and all the way down faster than you can imagine. Guided by a horst-Link suspension, poppy geometry, and 29er wheels.

The trail/rail flip chip adjusts the geometry to match the terrain. You get the right amount of anti-ride and anti-squat for proper braking performance and tire pressure. Also to maintain an ideal riding position. So the Reactor can handle anything.

Short travel means you can ride hard and fast with less energy. Many benefits come from the carbon fiber frame. It's light, strong, stiff and responsive. Always surprising you and getting you in and out of trouble. Gear up for the most daring mountain adventures!
