If you’re a rider that’s focused on shredding singletrack rather than bike parks, the Nukeproof Reactor Pro 290 Alloy is a superb mid-travel trail bike
Superb balance, insanely fast singletrack shredder
A little lightweight for burlier riders

The Reactor ST isn't as fast as some uphill, but it’s a proper demon when pointed back down
Surefooted downhill demon
Great spec at a reasonable price
Good geometry and ride position
Easy going but not as efficient as some uphill
Only slightly lighter than the top-spec Reactor which has more travel and a burlier build

Gravity fans watch out! Downhill, the Nukeproof Reactor 290C Factory leaves most of its competitors behind in a cloud of dust. The spec leaves no room for complaint either – we’re big fans of Nukeproof's approach of putting trail performance ahead of weight. But is this enough for the Reactor 290C Factory to secure our coveted Best in Test?
Well thought-out spec suits the intended purpose
Intuitive, balanced handling
Good suspension
Comfortable pedalling position for long rides
Climbing efficiency

Recently re-launched and now a full time member of the Nukeproof Reactor family, the Reactor 290 ST is a shorter travel version of the full suspension trail bike. With a lithe and resposive feel and top spec components, this bike – so long as you're happy to lock out the shock for climbing – makes a mean mile muncher. Merida One-Forty 600 review Vitus Mythique 29 VRS review The best ways to find new mountain bike trails As a 125mm full suspension trail bike, the Reactor 290 ST was designed for legendary downhill and enduro racer Sam Hill to ride in the off-season.

Designed as the ultimate hard-charging hooligan of a trail bike and conceived for those riders that are looking for ultimate speed and style out on the trails, the RS is slightly over-forked, featuring +10mm of travel up front over the rest of the range to excel when on the most technical and mini enduros and downhill trails. .

Nukeproof drop the Reactor ST; a limited edition lightweight short-travel version of the all-mountain Reactor with build spec worthy of an XC race bike.

Shredding trails since 1996

Nukeproof's take on the short/mid-travel trail bike turns out to be very capable - and tons of fun to ride.

I got a chance to demo the Reactor at the NW Tune-Up. I was coming off an e-bike demo from earlier in the day, which probably helped make the Reactor
Super playful
