To make the V1 stiff enough with the bridge around the front of the seat angle, we had to add more material to the layup which made it heavier. The new frame was done like this to achieve the desired stiffness in a lighter package. The old frame was 2.4 kg whereas the new one is 2.16 kgs (without paint) Although the Mega seat stay may look similar, they are different.

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.
