The Nukeproof Reactor Alloy Pro 290 is an aggressive trail bike, and we reckon it's one of the best choices around for UK riding. It's a blast around trail centres, but it's more than capable of handling a day at your favourite bike park too.

Modern, aggressive geometry makes the Reactor a strong climber and a rapid descender, and a two-position flip chip lets you switch between Trail mode for more pedalling efficiency and Rail mode when you want to shred. With 150mm of travel up front and 130mm at the rear on 29" wheels, it's the kind of go-anywhere bike that suits epic days where a 1,000m climb leads to a 1,000m descent.

The frame uses a hydroformed, triple-butted 6061 T6 aluminium front triangle and chainstays, paired with carbon fibre seatstays to reduce unsprung mass and optimise lateral stiffness. It's a great balance of low weight, strength and stiffness, finished with a RockShox Lyrik Select+ fork, Super Deluxe Select+ shock, SRAM T-Type 12-speed and SRAM Maven brakes.
