2020 Nukeproof Reactor switches from trail to rail in 30 seconds

by 4

Nukeproof enter the trail bike race after exiting the market for a few years with the new 2020 Nukeproof Reactor.

The Nukeproof Reactor is an old name attached to an all-new trail-orientated full-suspension bike. The original Reactor launched back in 1996 and was a hardtail with linkage for, the new bike is nothing like that, and features aggressive geometry, new carbon frames and a choice of wheel sizes.

An all-new frame has been developed for the 2020 Nukeproof Reactor, with new kinematics and geometry that ensure that this trail bike doesn’t overlap into the Nukeproof Mega’s territory. That’s not to say it isn’t enduro and gnarly trail-ready though, it’s just more trail focussed.

The new frame represents the first time that Nukeproof has offered a complete carbon frame with carbon chain stays and seat stays too. The only alloy part being the compact linkage which drives the rear shock for between 150-130mm of travel depending which wheel size you’re running.

Looking shreddy!

Smaller 27.5in wheeled bikes come with 150mm of travel front and rear, expect the flagship RS which gets 160mm up front, while the larger wheel 29er has 130mm of rear-wheel travel and 140mm at the front.

The carbon frames feature internal cable and hose routing, including options to run internal cabling for a rear shock lockout. The fancy bonded frames also come with rubber frame bumpers for protection and noise reduction. And like every good trail bike, the Reactor has room for a full-size water bottle in the downtube.

Reactor frames also benefit from a flip-chip that transforms the bike from ‘Trail’ to ‘Rail’ mode. As the naming suggests ‘Trail’ is for all-round riding, while ‘Rail’ slackens the front end of the bike and drops the BB height slightly.

Available in 27.5 and 29er.

Oh, and if you don’t fancy a carbon frame, Nukeproof is offering the new Reactor in alloy too. Full details of each model in the Reactor line below.

    Looks good but I expected the pricing to be better given the direct sales model.

    Nukeproof don’t have a direct sales model. They sell via Hotlines in the UK and into a dealer network.

    Was really very excited about these as a possible purchase for next year but the pricing is well off. I’d spend £3k on on yes, but Eagle SX and a Brand X Ascend dropper? Really the budget end of the spectrum. Don’t get me wrong I’ve had a Brand X dropper and currently have SX Eagle on my hardtail but it was sub £1000 not nearly £3000.
