20 reasons to buy

  • Wide 800mm bars offer riders stability climbing and descending on the Nukeproof Reactor.
  • Nukeproof offers builds in carbon or aluminum, allowing riders to find a bike that fits their budget.
  • Riders have the option of purchasing a Reactor with 27.5-inch wheels or 29-inch wheels. This allows them to select a model of it that best fits their riding style.
  • Experts were pleased that all versions of the Nukeproof Reactor can fit a water bottle.
  • Nukeproof offers riders a flip chip adjustment to the bike’s geometry. Riders can utilize the bike in the “Trail” or “Rail” setting.
  • The “Rail” setting on the Reactor slackens the head tube angle and lowers the bottom bracket for riders looking for a more playful, poppy trail ride.
  • The bike’s short chainstays create a fun and responsive ride through berms and turns.
  • Nukeproof specs beefy Maxxis tires on the Reactor. These tires are durable and provide loads of traction.
  • Testers were pleased with the long dropper post specced on the bike. All models of the bike have a well-reviewed dropper post from Brand X, BikeYoke or RockShox.
  • The bike's active climbing platform encourages riders to pick their way up steep technical climbs.
  • The Nukeproof Reactor is affordable for a bike of its quality in the trail/enduro category.
  • Harsh bottom outs are rare for riders of the bike.
  • A rubber downtube protector keeps the Reactor from being damaged by stray rocks or other obstacles on the trail.
  • The Reactor's ribbed chainstay protector minimizes noise from chain slap.
  • Experts found the bike light in weight. This made hike-a-bike sections of routes achievable.
  • The threaded bottom bracket on the Nukeproof Reactor is easy to maintain.
  • Internal cable routing gives the bike a clean appearance.
  • Depending on the model, 130mm to 140mm of rear travel with 150mm to 160mm of fork travel, allows riders to descend with confidence.
  • Experts were pleased with the linkage-driven Horst-link suspension setup in the rear of the bike. It offered riders fantastic small bump compliance on trails.
  • The Nukeproof Reactor has a long front center. This allows riders to keep the front end of the bike down on steep climbs.

3 reasons not to buy

  • The Nukeproof uses Sam Hill grips on the bike. Several experts reported these grips to be stiff and uncomfortable.
  • Some experts experienced difficulty with the tubeless tire setup on builds with Mavic wheels. These wheels are only found on carbon RS models of the bike.
  • Test riders experienced pedal bob when climbing on the Reactor.

The Nukeproof Reactor is a mid-travel, full suspension mountain bike. Testers found it ideal for daily trail rides and enduro terrain. The bike has an efficient pedaling platform on climbs, although some testers experienced pedal bob. The Reactor has beefy tires, made by Maxxis, that provide spectacular traction. With models available for both 27.5” and 29” wheels and carbon and aluminum frame options, experts agree that Nukeproof gives buyers plenty of choices. This ensures that they have a bike that is within their budget and that meets their needs.

Nukeproof Reactor 275 RS Review

As the top-end and burliest Reactor available, it’s not a surprise to see a list of hard-hitting components, even for a 140mm travel trail bike, considering Nukeproof’s gnarly, gravity-focused reputation.
