Nukeproof Reactor Pro 290 Alloy review: dressed for success - MBR

Nov 2021 · Paul Burwell

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

Highs
  • Superb balance, insanely fast singletrack shredder

Lows
  • A little lightweight for burlier riders

2021 Nukeproof Reactor 290 Carbon ST review

Dec 2020

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.

The Reactor feels like a bike with classic, old school all-mountain intentions, constructed with the colloquialisms of the contemporary mountain bike.
