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.

Nukeproof Reactor 290C RS on test – the enduro bike among trail bikes

Feb 2020 · Christoph Bayer

Despite having only 130 mm travel, the Nukeproof Reactor 290C RS was one of the most capable descenders in this group test. Its spec leaves no doubt about its performance and the geometry is spot on – but if the bike is so great, why didn’t it come out on top? Click here for an […]
