Nukeproof Reactor CRB RS 29 T-GX Mountain Bike in Red

Season:SS26

Brand:Nukeproof

Code:rec01asSramTransmissionGX

The Reactor 290 Carbon is a trail bike that thrives in technical terrain, both up and down.

Designed for riders who want one bike to do it all, the Reactor balances aggressive descending capabilities with efficient pedaling performance. From concept through to design, the kinematics, 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 tackling the most technical trails.

To optimize the weight, strength, and stiffness, the Reactor Carbon frame features a full UD woven carbon fiber frameset, including the chain and seat stays. This design is built for long days in the saddle, excelling on epic adventures where a 1000m climb is followed by a 1000m descent. Its versatile nature ensures it handles both with ease.

All Reactor frames feature a “flip chip” to adjust the geometry from “Trail” to “Rail mode.” The Trail setting is best suited for general trail riding, ideal for riders who enjoy the climb as much as the descent. The Rail setting turns the Reactor into a corner shredder, dropping the bottom bracket 6mm and slackening the head angle by half a degree to maximize descending capabilities.

To ensure the bike could climb as well as it descends, Nukeproof engineers designed the 4-bar Horst linkage to have higher levels of anti-squat for climbing gears but lower levels when dropping down the cassette. This combination of low anti-squat and progressive rate gives ultimate small bump compliance 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 pressure through the tire to ensure traction.
