Nukeproof Reactor 290 Pro Alloy 2022

We love the Reactor here at Biketart. Designed by Nukeproof to be the ultimate aggressive trail mountain bike we reckon this is one of the best choices for UK trail riding. Suitable for a blast round the UK's trail centres yet more than equipped to handle the much loved bikeparks you cannot possibly go wrong on a Reactor.

As a trail bike the Reactor is a strong climber and rapid descender and boasts modern aggressive geometry. All Reactors feature a 2-stage flip-chip to swap the Reactor between Trail (for more pedal efficiency) or Rail (Shred mode) settings and further tailor your ride to the location.

Available with options for nimble 27.5" or full speed 29" wheels, offered in alloy and carbon frame options as well as a range of awesome build kits, there is definitely a Reactor waiting for you. The 27.5" Reactor has 160mm front and 140mm rear travel where the 29" uses 150mm front with 130mm rear.
